No no no no no just fucking no (╬￣皿￣)凸 senpai where you at

One thing something is wrong with his mind or was he born like that
He force his brother then threaten him then he say he love him and his brother is broken heart and he thinks the his brother like him man this guy is sick I wish senpai will come and save him man that why I don't read this kind of manga it just makes cry non-stop ╥﹏╥

I think it's a mixture of something wrong with him and some caused by trauma from being raped by his teacher. Also potentially learning from her. "If you love someone, you can take them even if they don't love you back."
