Nikko Otsuka is a 17-year-old boy with short blond hair and gray eyes. He is introverted, prefers to go unnoticed and has suffered bullying all his life. He lives day to day with anxiety and depression tormenting him. His father left when he was young and his mother has psychologically (and sometimes physically) abused him for as long as he can remember. Are you going to be able to start a friendship with him or will you make his life miserable just like everyone else?
