What does “being perfect” mean to you? To Hashidate Yuuto, it means everything. All his life long he strived for perfectness until a single incident occured in middle school that ruined his plans of being perfect: He pooped in front of the whole class and parents. Believing, that his reputation was destroyed and that he would never be able to reach perfectness anymore, he wished that the incident never occured. This is when a mysterious Goddess named Maki offers him a button that allows him to go back in time.
