can someone be a cutie and summarise this for me I forgot everything 😔😔

I might be late but it’s about a boy who is an only child and has no dad. The boy gets a brother (adopted). This kid is very troubled since he come from a very abusive family, hence he doesn’t know emotions. The only child (who is not an only child anymore) corrupts the troubled kid even more because he ignores the troubled signs of his brother just so they don’t take his brother away from him. (I suck at explaining )

TYSM I REMEMBER NOW
