Driven by a profound sense of existential emptiness while living in Tokyo high school life—a feeling that his existence lacked true meaning—the young man drops out to stay with his Aunt Megumi in the countryside. It is here he unexpectedly reconnects with Akemi; his beautiful cousin whom he was once intimately close with during childhood. Years spent navigating city life had created an awkward distance between them. The initial reunion is laced with shy glances and hesitant conversation until Akemi breaks the ice by asking about his relationship status.
She playfully teases him about his still-unretracted foreskin—a jab that strikes directly at his pride. Determined to prove himself worthy of her attention and affection despite knowing she is happily married (or so he assumes), he decides to take charge of their reunion. He harbors deep feelings for her, recognizing the subtle unhappiness lurking beneath her marriage facade. As she begins to pull away toward her husband’s embrace,
the protagonist resolves that this moment, this intense connection forged in rural nostalgia, might be destined to fade into mere family history. Yet, before it does, he intends to make sure their bond transcends kinship and friendship forever.
