As children, childhood friends Sato Misaki and Takahashi Kaito made a promise: "Promise we'll marry each other when we grow up?"
Shortly after making this promise, Kaito seemed to disappear without a trace, leaving behind his school, his friends, and Misaki.
Six years later, Misaki transfers to a Japanese high school after her parents' divorce. Unfamiliar with her new environment, she tries to adjust as quickly as possible, attempting to make friends and fit in with her new classmates.
While trying to make friends, Misaki still clings to the promise she made with her childhood friend six years prior, despite believing that he has truly gone somewhere without a trace. Unbeknownst to her, her childhood friend had not disappeared and was closer to her than she thought.
