Saiaku no Jinsei

Kawashima is a third year high school student who's always had a shitty life. He has a violent personality so people constantly misjudge him and his actions. One day he meets Sayama, a first year who's good at everything but has zero ambitions in life. Thanks to his easy-going personality, he becomes the only person who's ever tried to understand Kawashima. These two will have a huge impact on each other's lives.
