Yuuki Hase is a high school student who wants to befriend his isolated classmate Kaori Fujimiya. Kaori keeps people away because memories of her friends disappear every week. Even after learning her secret, Yuuki decides to become her friend as many times as necessary. The two begin recording each week's memories so their connection can continue after each reset.

Shun Asakura has always struggled to express his true feelings, a trait that kept him from confessing to his childhood crush, Sana Wakatsuki, before moving away. Seven years later, Shun returns to their hometown, determined to finally share his heart. But his resolve is shaken when he encounters Ayumu Fujisaki, a boy who looks exactly like him yet embodies the confidence and openness Shun wishes he had. As Shun navigates his feelings for Sana and the mystery of Ayumu, he begins to question who he truly is and what it means to be himself.
