An expressionless classmate, Suzu, who has a college boyfriend in a long-distance relationship. One day during the winter training, Hajime is invited by Rin to have sex in the club room. "I'm glad I wasn't a virgin. Wouldn't it be a problem if I got serious?" Then, during the winter training, Rin and Hajime spoiled in the toilet and in the health room. Winter vacations that I can't return to, memories of a bittersweet bitterness of love.
