The player takes the role of Inoue Yuuta, a boy who returns to the town of Tokimori after ten years of living elsewhere. Seeing that his parents had gone out of the country on job assignments, Yuuta found himself sent to live with his aunt and uncle. Of course, things do not go as planned, since his own aunt and uncle had also gone on a business trip to Brazil, leaving his cousin Chizuru in charge of the house until they returned.

Yuuta's return to Tokimori is filled with numerous reunions. Aside from his former-tomboy cousin, he meets again with Kasugano Haruna, a girl that he used to know ten years ago. The sudden arrival of a girl named Tsubasa Miu sets the story in motion as Yuuta gets reacquainted with his past, the memories of his childhood, feelings of forgotten love, and the mystery associated with the town's local attraction, the stone spire known as the "Spire of Memories".
