MC is actually dying and in order to stimulate his brain, a system was created to let the brain continues to work. MC's original task was to make the female lead love him but in the first world, it was the ML who fell with him and system changed the task to making the ML love him.

In every world the ML fell in love with him and MC dies leaving the ML in dispair. This prompts ML of the stories to go beyond and search for MC.

There are different types of ML, the possive, the lustful, the cutie, the elder brother like, the yandre, the nice guy... Etc etc. So basically, they are different from each other.

It was then revealed that the system is MC's friend who loved him but died. Before he died, he volunteered to have his brain used for medical purposes, hence he became a system used to stimulate brains of critical patients. The system doesn't have emotion but he has some memories about MC. Each ML represents different parts of ML's love to MC. It represents his childish crush when they were young, his love as an elder brother, his care and hope for MC to live happy life without him, his pain of hiding his love, his anger cause of the taboo love as homosexual, his unrequitted love, his mature love, his lust, and his regret of dying without confessing to MC and not growing old with him.

This is why some ML is so annoying and some are adorable. it consist if MLs good and bad side only to the extremes.

I totally adore Ark the humanoid angel. He represents ML's crush. He is content to get a head pat and hug from MC. Totally meng.

When the MLs realize that they are just part of the real ML, they didnt accept it easily, but one by one they let go of it. The MC have to fulfil their wish to let go.

This is actually the sad part. I could really see that they love MC in their own way. When they started to let go of him, it made me cry.

I also adore Qinghan, the first to let go and accept the merge with the system. He represent MLs utmost care and wish for MC to live a happy life even without him.

In the end the system got all fragments and became the whole ML.

At first I thought that MC was forced to like the ML, but no. When MC saw the systems body, his intense emotion was trigger that it almost made his life in critical condition. It shows that ML is really someone MC loved. And the reason why MC wants to live and go back to the real world was because, he knew that losing someone you love is painful. He doesnt want his family to feel the pain he felt when he lost ML.

Worlds: The story has different types of world concepts depending on the MLs/MC and they're overall pretty good. We have MC being a vampire hunter who was forced to a blood-pact by a vampire, MC being a "god" in a dynasty full of devoted people, MC being a pitiful ghost bounded together by a ghost-tamer, MC being the "once in a century" genius arranged to marry a nobody, a nobody who'll walk the demonic path and take revenge just for him and try to bring MC back to life, etc.

Our ML is very hardworking - he's the male lead, the second male lead, the antagonist and the love interest all at once!

Fu Qinghan is my bias (he's so gentle and considerate and makes MC feel safe and secure) and he's the only guy to sincerely wish MC peace and happiness selflessly. He gives you second male lead vibes tho T_T

And yeah Jiang Che is my fav too because he's the most precious existence to Ji Ning and the one who he'll always choose. He's also interesting as a character because we readers get to know him through the other characters and he doesn't actually appear until the very end

All the male leads ended up as separate personalities in the same body, and switch around whenever they kiss MC. It's too much of a harem ending for me, especially when I was promised 1v1. Ignoring the extras though, the main story ending was very satisfying with how the personalities fused into one, as they all got their own emotional arc with MC!

There’s this twist to the merging of souls that I find interesting, how they’re mostly reluctant to lose their identities and past experiences.

they are all the same person.

I am disappointed that the author would use this trope. Not that it's bad per se, but just because that it's been done SO many times before.

I like it, although some had too little screen time compared to others, I still feel attached to all the characters, (ok I think not so much to lai 😥) anw, I love the 11 or 12 ML hehehe it was a bit of a pity that we didn't get to see a very clingy and sweet Ji Ning, cause through all the worlds and happenings he had his emotions blocked and in the real world it was too short, but it was still a fulfilling end. The worlds of the MLs were also really different from world hopping worlds.

Ji Ning - it's funny how his bias was really showing AHHAHA but I love him, honestly he is probably the one who did not have much flashbacks LOL, like we didn't really get to know how he really is because he is always acting and it changes depending on who he's with. I guess I kinda wished the block in his emotion was also a bit affected during all those complications but it wasn't lol, I guess he would have lost his mind if he didn't have that. I think he'd be too softhearted if he didn't have that emotion block. ANW, I love him

Gu Chen - I also like actors, and when I think about it, he actually got many scenes with Ji Ning, or at least I think so because of that holographic video, it was very intimate hehe. Also, Ji Ning was kinda pursuing him the whole time cause of his 'mission'. I like him, he tried too HAHAH and they said he as the closest to Jiang Che

Huo Wuling - to be fair, I didn't like him at first because of how weird he appeared, it honestly surprised me how the translator and author has him as their bias/favorite. I really didnt like him in his first appearance cause he kinda c*ckblocked gu chen and ji ning HAHAHA U know what I meann. Anw, as time passed, I actually believed he was the one who understood Ji Ning the most. Because of the many world kind of thing, and how he was always with him in his shadow. In the end, I liked him too. I love how he acted when it was said that they would have to fuse, he didnt wanna lose himself. I mean after all, he did get through too much. He also had been the most mysterious I guess? Like with the grocery store and all that. I like how he just fights everyone too lol, he does right?

Herinos - idk why but I actually really like him ever since his first appearance, opposite to huo wuling. I like how Ji Ning liked him too and felt bad for him. As a vampire, he was actually really sweet. Even his backstory is kinda sad but its because he really like Ji Ning. He even had a black room scene hehe Over time, he lost screen time tho, it was a pity. He's always awayy and we didn't get to know where he goes HAHHA I still love him, esp when he's getting angry or jealous hehe we love a vampire

Ying Qianqui - to be honest, I always forget his backstory, even now, I can't seem to remember what exactly it was about. Oh wait, I remember. He was the one where he didn't like Ji Ning at first and Ji Ning keeps on pursuing him, but when Ji Ning stopped, he missed him and yes, ok. I remembered him cause of the fight/competition scene and how Ji Ning is a devil (?) and he is the righteous cultivator or something. I also remember how the translator said that he was the only ML who Ji Ning didn't want to appear in front of cause he feels bad to give him hope when he would be gone when the world returns to normal. I also remember now that he was the one who plays the sound of Ji Nings voice in a recorder. OK. I remember now that I liked him very much too when he first appeared. He was also memorable with the other ML cause he was the quiet one.

Lai Senger - ok, he is the one I feel the most distant with. It's cause he's always in that game, and he did not have much interaction with the other MLs, I guess that made him unique and easily memorable but I like those interactions. Anw, he was also an enemy to lover kind of trope and he was actually a really OP ML. I remember him for his shamelessness especially for those choices he gave to Ji Ning lol, the ones with the square block ⬛.

Qin Ruwang - I liked him at first sight because Ji Ning was really worried for him. I'm happy that he got that fake happy ending/ illusion because he had too many regrets. It was really sad what happened to her mother and how Ji Ning had to leave him early. He didn't have too much scenes, I just know that I like him cause Ji Ning cares for him.

Ozer - He, I actually like him. I felt so bad for him cause the translator's calling him a scumbag, but his backstory was really cruel. He was even handicapped. And he had spiritual power problems. AND homos*xual love is forbidden in their world. OK, I definitely feel bad for him. It was also sad how Ji Ning was running away from him the whole time, when he just really misses him. I love him, yes, probably one of my fave, huhu, this really says too much about me. The way he realized his feelings for Ji Ning was really good. His status was cool too, everyone knows him hehe. Tho he was really a pain in the neck of Ji Ning HAHAHA

Ark - He's just a cutie pie, I love how he represented Jiang Che's first love, first everything with Ji Ning. He was really cute and sweet, and he even had a sidekick or something hahah he was also the only one who saw Ji Ning as a mermaid. It was also funny how he was dragged around, like from his world, to Ji Ning's apartment, to abroad, because they were running away from Ozer. Miss those times HAHHA He a really cutie

Zhou Rin - oh, this poor guy. Even his supposed-to-be-happy illusion wasn't that happy!! Ji Ning!! You tortured him cause you were so scared of getting pregnant! Huhu, I even like ABO but because of Ji Ning I didn't get to enjoy this world HAHAH. I feel so bad for Zhou Rin, esp cause he had that moral dilemma with his brother. And his brother even died 😫 how can he fight with a dead person! And he didn't really had a chance to begin with cause of their attitude towards each other huhu. He was so misunderstood, I was so happy when they solved that misunderstanding in Ji Ning's house in countryside. In the illusion, I was also real happy for Zhou Rin, but then he got attacked by that moral dilemma, and he actually made me cry 😭. I like how he got his screen time on that arc cause he didn't get much on the first one.

Yun Yuan - this one, I also feel bad for him. Wait, is his backstory the one I wrote for lying qianqu? Omg idk. I don't think sooo. He was the one who reincarnated to reach a higher level right. Imagine living peacefully but then getting bothered by a cute guy and then falling in love with that cute guy and when it's time for you to marry each other after all the hardships, he leaves you?? And he was literally minding his own business?? I feel bad for him but not as bad with Zhou Rin cause his sadness turned to anger lol. Its a pity that Ji Ning didnt seem so considerate with him, JN was always afraid of him. He waited for 2000 years tho. It was funny how Lai had to convince him to fuse with Jiang Che. I think he's the character who deserved better treatment from Ji Ning. Cause Ji Ning really flirted with him, while Zhou Rin fell in love by himself lol.

Fu Qinghan - welp, here's our ML who acted like a second lead lol. He was such an angel, it was cute how Ji Ning was so dependent to him cause he raised him as a fox. I remember him very much cause he was so good. He even left first in the end cause he just wanted Ji Ning's wish to come true huhu. What a good guy, and the fact that the author introduced him last!! This author really love the red flags HAHAHA his backstory was also kinda sad, cause of how Ji Ning said that he was the most powerful man under the heavens for just a while cause he died too lol. Also, it was a nice surprise how his Shizun is Yun Yuan lol AHAHHA I love him tho
