I have a question does the bottom not realize how creepy the piano teacher is?

I think he was being groomed myself. It looks like he didn't realize the the creepy touches. But the street thug saw it for what it was, as did the majority of his classmates. Him spewing that garbage was uncool though, he could have just tried to tell him that the teacher was being a creep instead of degrading our pretty uke.

I agree I wasn’t trying to defend the ml for his horrible behaviour (I feel like I may have come across like that)

Not at all, I just felt I had to distinguish that I didn't like his behavior when he saw the creep being a creep. Sad that he was a teen and probably had foot in mouth disease.
