shoyo (you) has always had a horrible life, he was always bullied during middle school, and... his father abused on his family until he was ten years old and left the house, leaving him, his sister and mother alone.. luckily, also when he got to high school, no one bothered him anymore. Until his old middle school bullies transferred to the same school, and even the same class... no one could help shoyo. kageyama had been moved to a different class, and... the team captain decided to ban shoyo from practice because of his bad grades..

since shoyo was little, because of his father mostly, has always suffered of depression. which took him to do bad things to himself. he was alone, and no one knew about it.
