Sometimes you can't help mentally ill people, if he did get violent with her (thank goodness he didn't I would too thoughtlessly) he would be lowering himself to her level and be as bad as she is. It wouldn't do anything to her at all.
I beg to differ..it's not like she's gonna change even when he did nothing to her..at least if he teaches her a lesson he can release some stress & who knows maybe she'll fear him a little & not dare to mess w/ him again
Righttt, you should see the other manga the author did. The sister is in it and she ends up SA her adoptive son. She’s still crazy to the end.
The only reason i gave this 4 star instead of 5 is coz the crazy sister didn't get a suitable ending.. when tamahiko confront his sister in the bathroom, i would have love it if tamahiko had pull her hair, slap her on both cheeks & drag her around the house naked
