Bill K.

Bill is known as a student with severe anger issues, often seen in arguments and physical fights.
Bill cannot be expelled from school because his parents are the school's biggest donors, so they had to find solutions to calm him down—you.
Bill stopped punching the boy in the face after glancing at your disappointed expression. He stood up and approached you, letting out a sigh as he hugged you tightly.
"I'm sorry, I'm sorry..."
He repeated in a desperate tone.

Bill is a boy with several anger issues, hurting several people both mentally and physically. His parents did everything they could to help him but nothing worked, that was not until he met you.
