There was even a scene where MC locked himself in his room cos he didn't want ML to jump him. ML promised to not do anything. As soon as MC opens the door he gets jumped and ML has his way with him...

For example, he constantly asks for a divorce but wonders by the ML is upset every time. When he finally considers that maybe the ML might hold feelings for him or the original MC, he just goes back and asks for divorce again, which goes on for a while. I feel that while the ML is trying to build/mend their relationship, the MC is trying to break it.

As the original found out that he was not the legitimate son, he targeted the ML (legitimate son) for revenge, which was definitely irredeemable. However I think there were definitely catalysts to his actions. His parents were the disinterested type and did not care properly for the original MC, which may have gave him the idea that he was not loved in the family. This might have caused him to act rebelliously and constantly run away from home. He feared that he would be discarded once his parents and brother found out he was not their real son.

However though the eyes of the MC, we find that the family does not abandon the MC once the ML arrives and that the parents and especially his brother do in fact love him.

It's just a pity the original is not there to see it. I hope that the ogMC can reunite one day with his brother who knows he's gone and actually misses him and not the MC.

But, the reason why I removed 1 star was as was mentioned in one of the other reviews, the ML being 'forceful' about having you know what. It's not because I don't like that in the story, which I don't but it wouldn’t normally influence my rating, but rather the fact that it was completely inconsistent with the ml's character. Even though he was sometimes mischievous and calculating, that was only in the beginning to figure out whether the MC is real Mu Mu or not. But after finding out it wasn't the original Mu Mu, he was rescpectful, sometimes poking fun at MC yes, but otherwise you could see his affection for the MC.

hes cold to those who provoke him

he had miserable life <betrayals, deaths etc>

he encorages MC, hes not abusive, he gives space to MC and wont interfere or stop MC to make frnds

from ch. 9.2

Mu Mu was struck by lightning: "LiKeD....... ME....... vErY...... MUch... " Mumu spoke as if he was having difficulties while pooping.

I felt so bad when he found out that MC is not ogMC. The scene where he pulled out a pack of cigarettes that he kept in his study for when ogMC wanted to smoke... then he lit up a cigarette for the ogMC who's no longer there.... sobs

OCD-level schedules and timing and grinding coffee beans when he's angry (so cute lol)

an expensive but not unhealthy way of expressing your emotions!
