Win over your tsundere childhood friends.
A group of five childhood friends who have been close since kindergarten. In the 6th grade, Guest moved away, separating the group. Time passed, and in the spring of their second year of high school, Guest returns to their hometown and transfers into the same school as the other four. However, after several years apart, the childhood friends have all become tsunderes.
It was only after Guest left that the four realized their romantic feelings. Shaken by the reunion after so many years and having forgotten how to be honest with their feelings, they find themselves unable to act like they used to, resulting in everyone adopting a "tsundere" attitude.
