Mana and I belong to the same university volleyball club.Half a year has passed since we started dating.One day when the annual spring training camp was approaching, I accidentally injured myself.In order to concentrate on treatment until the tournament, Manadake will participate in the training camp.It's true that he trains hard during the day, but it's the night that's scary.There is no morals in a party of sports clubs who drink heavily.Club activities are a representative of a vertical society, and this time, OB Takeda senior, who was famous for being a libido demon, is supposed to participate.
