Taki Yuina's husband and Naoki have been close friends for years. When Naoki goes through a divorce, the couple decides to visit him in hopes of easing his pain. That night, the three of them drink and talk at Naoki's place. Since Yuina's husband isn't good with alcohol, he falls asleep early, leaving the two of them alone. As they continue drinking, Naoki tempts Yuina, drawing her into a forbidden encounter that crosses the line—offering her a fleeting escape, even as trust unravels.
