After being cheated on by her live-in boyfriend, Arikawa Misumi starts a new life alone in a small apartment. She soon runs into Kanna Iori, a man she secretly admired during her school years. Their encounter seems like pure coincidence at first, but Kanna keeps appearing in her daily life—even at her workplace. He has a way of seeing through her emotions and saying exactly what she needs to hear, gradually breaking down her defenses. Misumi finds herself willingly surrendering to his overwhelming attention. Kanna makes his intentions clear: “I want to spoil Arikawa.” However, the true nature of their reunion is later revealed to be far from accidental—this meeting was engineered, and Kanna’s possessive, obsessive side begins to surface. The story follows Misumi as she is drawn into a consuming relationship where she is both melted by his affection and undone by his fixation.
