Kunimi, who got married just last year, had dreamed of a happy married life. But her husband's attitude suddenly changed, leaving her feeling lonely day after day. Before marriage, they used to spend holidays together and enjoyed plenty of time as a couple. Now, however, her husband leaves early in the morning for fishing trips and, upon returning, they go their separate ways. With communication completely broken down, she suffers from sexual frustration. Seeking to ease her loneliness, she contacts her ex-boyfriend and begins an affair. Being with another man again after so long is intensely exciting, awakening long-suppressed desires within her. Driven by this newfound thrill, she soon finds herself pursuing yet another lover.
