The way MC is being delusional about a whole different place, whole different people (strangers that he created and act the way he want), the comforting words and praises.

Always looking forward for the next day, sayying things like "there's always a tomorrow" when he doesn't really have a fixed purpose.

Forgetting things he just did a moment ago, forgetting people he used to know, but remember his only reason to live. Talking to himself as if there's people around that would be kind enough to respond to him.

The basic situation of the Luo family that led to such unfortunate situation comes from his own mother. She has HPD (Histrionic Personality Disorder), but she's not a patient and was never treated. She refused to accept her own guilt when she lost her two children, Luo Zhi and Luo Cheng, just because she got angry with her daughter Luo Cheng, she left her two children without care and in this time period both children got lost. And because the reason for her losing children was so shameful she refused to accept it and put it on herself. The daughter was returned first, only a month later. As we later find out all thanks to Luo Zhi. But Luo Zhi himself returned home by himself three years later.

What happened during those three years? Mrs Luo played the victim and shifted blame on her son, repeating many times that it was him who was responsible. What are unfortunate circumstances? Mr Luo condoned his wife's behavior, because he was extremely face-loving. He was the one who took Mrs Luo to the orphanage and adopted Jian Huaiyi. Eldest son was abroad most of the time and had weak relationship with his brother and sister, but returned after abduction, so his connection with adopted son was more profound, but he's eventually more like his parents and also refuses to accept faults about himself that he chose to believe adopted son in every situation, even if he knew the truth subconsciously. Luo Cheng was too little to form an opinion and the lie told too many times became the truth for her, she believed it was her brother at fault, though had her own memories and also knew it was her brother who saved her, but eventually forgot them.
Mrs Luo's condition was so bad that she was hysterical every time she saw Luo Zhi. Even the child's name was changed to Luo Zhi from Luo Chi because of his mother's condition. He was blamed left and right, even he was just a kid of 10 yo (7 when he was abducted). And this blame continued. Entire family called him out for being not able to make entire family peaceful, although it wasn't his problem and he didn't do anything. Mrs Luo was always acting hysterical, but the point is - she made herself sick, just to shift blame. Eventually the entire family took the title of "victim" from Luo Zhi and they became the victims of having someone like Luo Zhi in the family.
Funnily, through reactions of others, which come much later, there is a character of Dean Xun Zhen, who will work with Luo Zhi on his psychological condition and he shared opinion of his wife, who heard too many times Mrs Luo spreading the fault of her child and she thought how mental you should be to blame the child, so she ceased any further connection with Luo family and asked others to do so as well.
The situation continued before Luo Zhi turned 23. His company he brought back from bankruptcy was taken away, here comes the situation where he was blackened by entire network and was accused by one of the artists (mentioned in the summary). Everything looked like someone's plan and a clumpsy plan at best, but his family was so used to shift blame that his younger sister was thinking that it's best for her brother to simply die and not drag her family down. At that time Luo Zhi asked his sister - at the moment when he almost died, did she really think that it was his self-acted performance? But deeply inside she really hoped for it. Why? Because she was simply the copy of her mother, one of the symptoms are being too gullible, not liking to be pointed at their faults, forming their own strong opinion no matter how problematic the reasoning or shallow the logic, having shallow emotions. So when someone called her cold-blooded, she was indeed one. And there were two helpers who continued to feed her idiot head these ideas. Jian Huaiyi and Ren Chenbai.
Jian Huaiyi was actually not even a big opponent when it came to means, but he fully realized the characters of people of the Luo family and utilized knowledge to his advances. So you could say those poorly and theatrical frame-usp happened, but because Luo Zhi was the dumpster for blame no one even doubted anything.
But Ren Chenbai was scarier I suppose. Who is Ren Chenbai even? He is the son of Aunt Ren (Ren Shuangmei), she was the only light in Luo Zhi's life after he returned, she was friends with Mrs Luo, but she couldn't understand why her friend could do this to her own child. She basically took Luo Zhi away and everyone in Luo family was happy. Luo Zhi was only 10 mind you, he just returned, he lived with psychological and physical scars, aunt Ren knew about it. Unfortunately no one in Luo family bothered to read the transcripts and files. Broken ribs, head trauma, loss of hearing in one ear, the list goes on. Aunt Ren became his family and brought him back to the light. She refused to call him Luo Zhi, she called him Little Flame, like she used to. She taught him painting and guitar, she took him to different places and became the closest person to him. But what she didn't expect was that she suddeny fell ill and she had no time to correct her own son's behavior she noticed. Her sudden passing was a shock. But Luo Zhi was unware that Ren Chenbai refused to admit his own fault in the matter that it was his fight with aunt Ren that led her to have accident and the saving was untimely. The Ren family accepted this fault and placed it on Luo Zhi's head. Any tiny bit of investigation would prove it wrong, but Ren Chenbai was always someone else's child, future heir, so they protected their own shortcoming. Ren Chenbai deeply believed his own conviction and played a great role in trying to destroy Luo Zhi's character, his relationships and become the only one for Luo Zhi to rely on, so he could do everything his sick mind dictates.
We come back to the present and accusations. What comes unexpected is that Luo Zhi becomes gravely ill. But Luo family doesn't care and Ren Chenbai hates him too much to even bother to cure. Only Luo Zhi whose condition drastically deteriorated escaped and tried to move forward and fulfill his promise to aunt Ren, that he will one day be free to follow his dream of travel. One simple desire kept him going. Even if he barely could move, he lost hearing, he could barely see silhouettes of people, suffered from headaches.
Luo Zhi had a brain tumor. His condition wasn't news if you think about it, but he postponed hospital visit many times. Why? Due to the company. Why he even bothered to save the company? Because he was still a kind human being who cared for his sister, she wanted to become a celeb and he wanted to create a company as her backing. Even his money for a cruise ship he spent on a script because Luo Cheng needed it, the same Luo Cheng who refused to accept him as a brother, avoided him, even took pleasure in punishing him because she felt it's justice. One of the parts of HPD is also not realizing your own mistakes and how problematic things you do are.
Luo Zhi's condition got worse and worse, but no one noticed and everyone did not think he was unwell, even Ming Weiting who appeared later thought he was fine, because Luo Zhi acted as normal as possible, it was his habit - don't worry about me and stay away from me not to be implicated.
Luo Zhi finally happened to be on a cruise ship, we find it's Ming Weiting who helped, but the entire Luo family was also there and suddenly the ship meets an accident. Due to quick actions of the crew the process of saving passengers went excepionally well. Some missing people were met later. But there was only one person who was claimed to be missing - Luo Zhi. And even if he happened to be close to Jian Huaiyi and Luo Jun, Luo Jun was too dismissive of this brother his entire life that he even forgot about him. This is to give an overall view of the family through their actions.
For the next period of time we mostly hear about Luo family and the consequences. The other part belongs to Luo Chi (this is how he was called among the Ming family) and his recuperation. Luo Chi entered a complete stupor, unresponsive state and barely walked out of it to recuperate physically and mentally getting ready for the operation. Why Ming Weiting cared so much? Actually both of them had a past. Ming Weiting is now and orphan who controls the entire Ming family, they own ships, his only relative should be an old man Ming Lu. Once when he was younger they docked at this same place and were attarcted by a bonfire and guitar music, a young boy, then young Luo Chi, came into contact with a bigger crowd after a very long time and he played the guitar and was surprised to find how many people liked it. That's right, his perception of being liked changed drastically due to his family situation. Ming Weiting was attracted to it. But he felt there was no need to investigate the boy, because the boy looked happy, if only he knew he'd take the boy away back then. And this is why he was the one responsible for actions against the Luo family. It wasn't anything excessive, but you can guess that few moves might bring the family down and if the family is not stable from within it will fall apart even faster. No one realized that this family could be loving and happy just because Luo Chi was their common "enemy". After Luo Chi was gone for them, they became enemies of each other and many undercurrent things resurfaced.
Recuperation and post-op period do take quite some time. At this point when Luo family slowly met their worst nightmares it felt like things really slowed down and felt like author spends too much time on it. But you know that this is the period that would make Luo Chi inevitably fall in love with Ming Weiting. And interestingly, there is not a word of love actually, it's so subtle through reactions and tacit understanding, even later no one confessed but when they went to meet a woman named Zhao Lan, she was the one who survived with Luo Chi, one of them said - she will come with her husband, how coincidental (meaning they consider each other husbands in their hearts). But it took a while and I can't say much, it was like an emotional guide. It's very fortunate that Luo Chi met Ming Weiting, person who could provide and truly cared, because Luo Chi was in such a bad situation, only utmost care could turn him back. And what is more realistic is that it's a tumor and there are risks explained and what's more after the operation Luo Chi, who changed name to Ming Chi, suffered from sequale. It's not all sunshine and flowers that are skipped and not mentioned in many books, but you actually feel the process and care and how much patience it requires and it fully showcases the care and love. Although it felt tedious, but maybe that was the point. And the main sequale is the memory loss. But in Ming Chi's situation it's not even a bad thing, he could forget the entanglement with his family, because now he does not have the immersive experience, he's just a viewer from sidelines. And even he forgot Ming Weiting too, but he remembered him instinctively, even physically (being helped and held, because at that time he couldn't move). But now he could see his Mr. Shadow who was only a blob of color for him before and now he could hear him. He felt truly happy. He remembered the best from aunt Ren. He made himself so many notes, so many preparations to remember other people who cared about him. Slowly he taught himself of what he is, what happened and decide what to do next after recuperating.
What is lovely is that Ming Weiting never wanted to fully capture and never let go of his little Flame, he knew that for little Flame to continue to be bright and happy he must be freed. It was this type of love where he could accept anything Ming Chi would decide on, travelling by land, by sea, meeting new people, drawing and playing. And he was ready for any status near him, as a family or as someone closer. Now they were not afraid to let the world know that little Flame survived, because during this time the opinion on the Internet reversed. Like he himself said after everything he had done: "It was the course of fate that was unfair to you and caused things to twist and turn. We have corrected it now." The other thing is that the little Flame didn't want to go.
So you can get such a portrayal. Ming Chi is a ball of kindness and happiness. Kindness is not a weakness. Luo Zhi was kind but shackled. Yes, it is his kindness to his family that he stuck around, but he continued to be disappointed again and again and later stopped caring, he only cared fro what was left after aunt Ren, he decided to fulfull his dream. For him it was Aunt Ren who was his family, his mother, the car she gave him was his home, later it was Ming Weiting who became his family. He could recuperate and return to the world as Ming Chi, without his shackles and burdens and blame. People at the company became not only subordinates but friends, were the ones who fought for him when the company was jeopardized. His family on the contrary was not, even black materials that he used his background was ridiculous to them, all his misfortunes Luo Zhi suffered because of his family. In all these years he did not get anything from his family neither emotionally nor financially. Ren Chenbai who he considered the closest and wanted to stay together treated his as enemy and although RCB always acted gentle the malice could be traced. It was Luo Zhi's kindness that allowed the situation to go on, but actually protected these unworthy people. Just becaue these people are bad it doesn't mean he should stop being kind.
Do these characters need redemption arc? I think not. In many novels characters like these can have a wake-up call or just have shallow discription how they went crazy from regret. I think I like how author described it here, after all in many cases it confronts to the settings too. Mrs Luo, for example, bit back her favored adopted son she doted on because she was told he will leave her, she made a fuss of finding Ming Chi and finding a doctor for him (when it became known that he was alive), but for her own selfishness. Luo Cheng who is like her mother only later realized why company people treated her weirdly, they considered her the biggest traitor, she was made to apoligize, but she always tried to shirk her guilt and even if she admitted her fault it doesn't mean she admitted it in her heart, she could have continued to blame Ming Chi for letting her go through this and not coming and saving her from misery (funnily she wanted to enter entertainment because she was told by Jian Huaiyi that family will sell her and she believed it, but in the end it was Jian Huaiyi who almost sold her). Luo Jun was the only one hit by the regret and knew that it was the problem with his character that allowed such situation, he refused to believe that he made the wrong choice. Luo Chengxiu (father) knew that it was his love of face that allowed his wife to dominate the household. But knowing and accepting or reflecting are two different concepts. It became the situation where dog bit the dog, he as a father did not trust his children with assets, but was almost cheated by adopted son. Jian Huaiyi entered the game, because his means were not that smart. The little star also faced court due to defamation when Ren Chenbai shared the evidence, even if he was one of those who were aware of the plan, but he went crazy when heard that Luo Zhi died. When I finished reading I actually felt balanced, because the background work was done well to me and I knew what for all these people suffered the backlash. As it happened sooner or later the downfall would have come. And there is a recurring idea behind it - what woould happen if you just didn't try so hard to blame Luo Zhi for simply everything. But there is no "if".
So this is the story of Luo Zhi, Luo Chi and Ming Chi. Although I give the main idea I skipped a lot of things. So if anyone wants to give it a try you know what to expect :) Don't forget tissues.

Nope, because he lost his memories entirely about them and the story doesn't really show him regaining memories of his biological family.

Luo Chi, the one who was harmed, the one who felt the pain and rejection, the one who could forgive, drowned in the icy sea. Now there is Ming Chi who doesn't know who the Luo family is, has no emotional ties to them, and can't even recognize them when they show up before him.

Funnily enough, MC actually had things set up where even after he was gone he basically got revenge himself without needing much help from anyone else. In the end, an old family friend brought him a car that was of the same limited edition batch as the one his aunt bought him. This car was even renovated and modified based on his drawings and design plans to match as closely as possible to the car that was destroyed.

Also, his dad did one good thing for Luo/Ming Chi even if it was motivated by his selfishness. When Luo/Ming Chi's crazy mother wanted to go find doctors to restore Ming Chi's memory and wanted to go find Ming Chi, the dad reminded her that he cares the most about his face/pride. If she dared to do something that shameful (by trying to meet Luo Chi and get Luo Chi's memories back so that Luo Chi could forgive them), then he'd dare to grab her and jump off a building with her for a double su*cide/mu*der. That shut her up quick and she never dared to try to kick up a fuss or suggest looking for Luo Chi again.

Good job. Even if it was motivated by pride, you at least did one good thing for Luo Chi. I'm sure the ML would have blocked any attempt had mother gone through with it, but you saved ML the effort.

By the end, MC makes an almost full recovery after the surgery.

MC after getting rescued from the shipwreck is in real bad condition. His condition is so bad that surgery to remove the tumor is likely to kill him. In order to get the best possible results from surgery they have to weigh getting the tumor out as soon as possible and the state of his body to see if he can survive the surgery. It takes something like 15-20 days for them to raise his body to the best condition possible so that he can go through surgery. The surgery is a success and he recovers extremely fast due to his own desire to survive and how hard he works on rehabilitation. By the end, he's able to run without a cane for a bit.

From what I understand, this is within a few months of the shipwreck. And he has goals to live to a hundred with ML and travel the world, play his guitar at impromptu beach concerts, and try surfing, diving, traveling to the Caribbean, hang-gliding, and mountain climbing and so much more. He also has plans to spend New Years with the family of the girl who escaped with him.

The girl has found a husband who loves and cares for her, scars and all. The girl's family also say they really like him and that they will always consider him as family and they'll spend New Years together, celebrate all the birthdays he missed with him if he wants and they'll do all the things he dreamed of doing when he was kidnapped. (The college-age girl who escapes with him remembers all the food they fantasized about eating as soon as they got free, as well as the birthday cakes they'd have to make up for the 3 years of kidnapping, how they planned to sleep for days in big beds, etc.) Even after 13 years, she remembers it in detail. When they finally meet up again for dinner, she orders all the food he mentioned then and even the amount of food that was mentioned and talks in depth with ML about what the MC needs to pay attention to due to the past injuries when they were kidnapped.

The people from his company meet him by accident and are thrilled to see he's in good condition. They tell him that his office is still there and will always be there. Whenever he wants he can come back, the company will always be there for him and they are also his family. They tell him that if he doesn't want to come back to work, that's fine. They managed to buy back most of their stocks and give him 51% of the total shares so he will still be the owner. They tell him if he doesn't want to work, then he doesn't have to. If he wants to be an artist, he can be an artist. If he doesn't want to, he doesn't have to. If he wants to freely travel the world, he should do that. No matter what, they just want him to be happy and they will always be his backing. They'll do their best to do well, grow strong, take care of themselves, and they'll grow so strong they can take care of him and let him live the life he wants to live too.

MC's health had, expectedly, deteriorated very badly to the point he can barely see and hear. So even then there's barely any solid meaningful interaction between him and ML! It's just ML taking step by step action dishing out subtle revenge and trying to heal MC, sigh. I mean, I just want some nice healing interaction. But it's mainly what's happening to the other people (in their perspective) and then what ML is doing, and his mostly one-sided interaction with MC.

Ren Chenbai suffering more, but in a way, having to watch the MC living so happily and so freely with ML while he can not do anything about it was the ultimate torture to him.
