Runa Ookamigawa is a beautiful and perfect student council president. She is scary when she gets angry, so the frivolous and incompetent vice president Yuuga Tsukiyama calls her "Wolf-senpai." The two are like the moon and the turtle, contrasting with each other and not getting along. One day, Tsukiyama finds out about Wolf-senpai's true nature through a secret part-time job...!? The mismatched love story of two people with secret faces begins! (Source: Shogakukan, translated)
