SPOILERS:
kid dies at the end, the bully throws him off the rooftop, also the bully grows up and becomes a mob and rapes boys that look like the bottom. honestly a sad story with sex thrown in.
I think the Uke just wanted to get away and then pushed himself off of the bully so voluntarily jumping, it wouldn't make sense if he threw him off since he was in love with him and literally the only one who didn't make fun of the Uke after being found out! (he even ripped off the photos)
He dragged him out of the classroom to protect him but the Uke wanted to die at this point.
While the bully had a bad personality, I believe he was truly in love and not as much of a bad person after all.
latest story the ears are so big
