The series centers around him, his fate, and the efforts of his friends to fulfill the wishes of a letter from the future.

Kakeru is initially shown to be quiet and reserved, however, once Hiroto Suwa and the others invite him to join them on their walk home and hang out with him more, he seems to open up and enjoy himself. He enjoys video games. Though he puts up a happy front around his friends and family, he hides his true feelings often and is incredibly depressed over his mother's death/suicide, in which he blames himself for it happening. As the story progresses, he finally lets some of his feelings loose to Hiroto Suwa and Naho Takamiya, though even after the incident, he seems to still believe his feelings are only a burden to others. He is also very hard on himself on a consistent basis. He claims to think about killing himself every day. He is also a skilled runner and is the fastest runner in his class.

Everyone has regrets in life. So who wouldn't take the chance to change the past if given the opportunity? When sixteen-year-old Takamiya Naho receives a mysterious letter, claiming to be from her twenty-seven-year-old self, her life is suddenly thrown into flux. The letter tells her that a new transfer student by the name of Naruse Kakeru will be joining her class, and to keep her eye on him. But why? Naho must decide what to make of the letter and its cryptic warning, and what it means not only for her future, but for Kakeru's as well.
