Kazunari, a quiet and well-behaved young man, works at a printing company. On the other hand, his older brother, Takushi, is a short-tempered, typical troublemaker who was just released from jail. Yuria, a hard-working lady at a local printing factory has a young sister, Mako, who is very attractive and popular, unlike Yuria. The life of these brothers and sisters comes across suddenly, and two pairs of cat-and-dog siblings accelerate their fight.
