Main character (MC) rebirth back to his 6 year old self, goes back w/ Mrs. Mu to Mu family & from then becomes a good child to his step-mother who loved him previously & good elder brother to his half-silbings. MC is very smart & capable, especially since he took down the big Mu family in his previous life, so in this life, he becomes extra caring to repay the previous life's debt & enjoy the love from them.

He meets his lover early when he was still 6 year old who's was the genius that went head to head against him in his previous life. Of course, MC with his old soul, feels like he bullying this child genius and their relationship begins from there. Through each interaction, they gradually understand each other and their true selves are revealed.

MC especially suffered from the matter of the engagement, which subsequently led to ML leaving him. First of all, in this situation, I feel MC definitely suffered more than ML. He couldn't possibly throw his sibling aside, and he never actually intended on getting engaged. However, ML didn't listen to a word of explanation and closed himself off completely.

That's why I don't know why ML & his parents are SO upset. Yes they can be somewhat upset, but ML also just left without hearing about MC's plans and trusting in him. He seems like he trusted, but he turned around too quickly for it to be considered actual trust. Not to say I don't understand; MC has all but served up his bloody heart on a silver platter for the Mu's, so I get why ML might be worried MC would pick them, but still. Since he left without giving MC a chance, it doesn't make sense to me why they're so upset w MC when ML was also in the wrong.

Also, I actually hope mu yiqi & yan yu won't be together. Life is not always happy, and especially considering all that MC sacrificed for MYQ to be happy, it makes me low-key satisfied that MYQxYY won't end up together. They had a chance, but neither was willing to chase after it. Not that I don't like MYQ; even though MC suffered so much, it's hard to dislike MYQ, especially since MC was willing the whole time.

In his previous life, his biological mother brainwashed him from the age of 6 to hate his father's current family so that when he had joined his father's family, he thought they're out to get him. he wanted to take over his father's family business and destroyed the family in the process. He later realized his father's wife truly tried to care for him as an adopted son and his step siblings weren't malicious at all.

MC, I felt very sad for him. I know that he is atoning for his wrongs on his precious life. But it just hits hard. Its good that MC's sister was very clear on the sacrifices made by MC for them. How he has done everything in his power to protect and shield them younger siblings and their mother. I was very happy to know that someone is seeing this, and know this, and they were also hoping that MC get his own happiness.

MC's bro, yo, I really dont know how to feel about him. He is very naive, thats why he does everything he wants when he wants to, at MC's expense. Im glad that he and YY didnt end up together, but was also glad that in the extra there is a possibility of rekindling their feelings.

Scum dad, oh gosh, I just want to strangle you if I could. Being indifferent to MC, threatening him, saying bad thing about him to his brother, using him, is already to much. Now when he looked for MC's brother immediately after seeing MC when he was just saved, it just broke my heart for MC.

ML, I love their transparency with each other. He knows MC is deeply devoted when it comes to the 3 mother and children. He knows MC is definitely not a good thing. He knows MC is scheming, manipulative, paranoid and kinda crazy. He knows that MC's family will always be a priority for MC. Oh, he knows it all. But he fell for him anyway. And I feel like he is the balance here. MC's couldn't wait to die for their family, but ML was there to balance it out. MC finally have someone to look after him.

His existence as the Half-sibling. The Illegitimate Son.

He (MC) was raised by his abusive grandmother since birth, on day he was nearly beaten to death and sent to the hospital. Mrs. Mu who is compassionate torwards children saw him, who looked so similar to her own son in such a miserable state and was shocked. She felt the need to protect him and wanted to adopt him knowing he was her husbands illegitimate son, but was intercepted by MC's birth mom who suddenly turned up. 6 year old MC was naive and followed his birth mom who played loving sad mom act and so Mrs. Mu couldn't do anything. He was then raised and manipulated to believe that Mrs. Mu looked down on him, she destroyed his mother's happy family life and his half siblings wanted to take everything that rightfully beloved to him. When he was 14 years old he was 'finally' adopted into the Mu family. He then slowly destroyed this family from within, including the kind and genuinely caring Mrs. Mu. Later on he had an illness and died in a hospital reflecting and regretting his decisions in life, but then he unexpectedly woke up at the age of 6 heavily injured. Meeting Mrs. Mu for the first time again, he swore he would protect her and everything dear to her.

Now in this new life he immerses (and enjoys) himself in the role of a child, but is inwardly calm and in control. Only the eccentric ML can break his calm and take a loss. I love the childish interactions of MC teasing/threatening ML with a kiss after taking a loss.

"If he (=MC) really treats me as his father, why isn't he trying to talk to me? He thinks that I can't tell that he genuinely likes my wife, but is reluctant towards him? What a little brat!"

I don't have a fundamental issue with gong MCs because they're gongs, I have a dislike of them when they are written to conform to gong ML stereotypes that I personally dislike or find unrelatable. This one, for instance, has a teasing MC who likes to push the ML's boundaries, and also seems like he'll stereotypically be the one more eager for s*x while the ML will be more innocent and reluctant. A fairly common dynamic in these stories, but one I'm quite weary of. He's not otherwise a mean or particularly selfish character generally nor to the ML, but I personally find it hard to enjoy or root for an MC who is knowingly inflicting this arrogant and selfish behaviour on his uncomfortable love interest. It sours for me what is otherwise good.

I honestly have never really understood the persistent appeal of this type of character, but I do know they appeal to some or else they wouldn't continue to be written and translated, so rather than saying these traits make this a bad story, I would say they make it a bad story for me. If they weren't so gung-ho about making gongs like this, I wouldn't have a particular objection to reading a gong just because he's a top in bed.
