Pain (Assassnation Classroom)

Pain is about how an any pronoun person finds herself in Class 3-E. He has to kill their teacher, keep her music career afloat, and hide his bruises and scars that came from their abusive family from her class. He is suicidal, has social anxiety, and starts to have a eating disorder. Hates talking to people that haven't proven themselves not a threat to her. Will he make it out alive without dying from the abuse or killing themselves? Will she keep their music going? Will he kill her teacher? Will the class find out about the trauma they have been through? Is she going to be okay? Read to find out.

Sorry if it's hard to follow because of the any pronoun thing. I just wanted to shine some light on them.
Most songs will be by NF or Xxxtentacion that he sings.
This is also my first book so sorry if it sucks ass.
