idgi did Uke get like assaulted by that skank lady or was she beaten by her boyfriend (uke...

I think he was assaulted? That's how I interpreted it.

ugh that’s so gross she should burn. but why did she scream at the boy to stop his dad tho?

I think that stopping his dad was referring to stopping him sleeping around (it even says that it was a part of his performance, so this is how his music became so good or something, it was mentioned earlier - he was basically channeling his hookups into piano).

Sensei must've had feelings for the father and when he started ignoring her and went with other women instead, she used his son as a substitute.

I hope that I'm getting this righ. Someone correct me if I'm not, that part was definitely written in a slightly confusing way.

man that’s so gross glad she’s sad lmaoo she should die tf

True dat
