Personally I somewhat can't forgive his parents. Giving him the pills cause it seemed like they were considering how they would look having a son like that. Rather, than was would have been best for him. And I think those pills weren't considering he will die if he doesn't take them. Not to mention, He is an outcast on both sides.
Forgive me if I’m wrong, it has been a while since I last read this. I was able to understand what his parents did because well at the end of the day they are still his parents, what he gonna do? Cry ? Be angry? Nah grudges are no good for anyone and more for his weak ass. I saw the actions his parents did as more of a way of protecting him of society, if they were so afraid of their position & reputation in society and how others would view them, I don’t think they would have adopted him and gone so far to change his fur color. And yeah they don’t say if the pills will actually determine if he survives or not, I was just assuming he is going to die because it sounds kinda logical as his body is already used to it. And I was glad he accepted that given the fact in most mangas it goes like “ I don’t care if I die! I refuse to be someone I’m not”.
I love this. I wasn’t expecting him to just accept the fact he can’t actually survive without the pills and how his parents still love him after all they did, it’s so realistic and cute!
