need help finding a manga!!

Its been a few months so i cant remember the name of the manga or the first 2-3 stories. but the final chapter is a story about an abusive student who took advantage of his school counselor/therapist and would beat him. the manga ends with the student beating the teacher and the teacher begging his neighbor to let the student go.

i think one of the chapters in the manga also had brothers/twins and one of them dies?? idk but it was a manga with multiple stories in them. if anyone knows the name of it pls tell me its been killing me. ╥﹏╥
