Exactly my feelings are the same. I like this manga for siblings love but hate the parents. They don't behave like parents. They acted like step parents to Sakuya. In my house all of us siblings have similar likes and it's not like we copy each other and our likes are influenced by our parents and atmosphere. So I don't understand how the parents became so against one twin. To me it was the parents that needed to see doctor and they were the one who made Sakuya jealous and unloved which resulted in him doing what he did. Really hateful parents till the end. They didn't realise their mistakes or apologised for their wrong treatment of Sakuya. So I feel unsatisfied with them. They should repent for their wrongs.
First off just wanna say I love both Sakuya and Aya. Buuuuuuuuut.....
No matter how many times I've read this, I always end up hating the parents more and more. They didn't even treat them equally and after the accident they even go as far as sending him away!? Like seriously your kid made one mistake, and hes still only a kid instead of putting all the blame on him try thinking why he even did it in the first place. They didn't even try to understand why he did it, instead the mother went crazy and the dad sent the younger son away. Then later on when he sees him again, he kept on saying 'for my family' which ended up making Sakuya ended up having to say 'your family'. He didn't once say 'our family' which makes it sounds as if Sakuya isn't even his son anymore. He abandon Sakuya then he ended up having to go to him begging him to go help Aya. It makes me more pissed off that he not only sent Sakuya away but he even say Aya is the only child. I love this manga but I honestly seriously hate the parents they don't even act like how real parents should act at all. I wish there was more parts of Aya going off on both the parents how awful they were for treating Sakuya like that. And have the parents reflect on what they did wrong.
