Newlyweds Kotoko and Naoki travel to Hawaii for their honeymoon, where they meet fellow couple Horiuchi Mary and Takumi. Mary attempts to sabotage Kotoko and Naoki’s relationship by constantly inviting Naoki along on her activities, causing distress for both couples. On the final day, Kotoko proposes they spend time alone, but Mary feigns illness to summon Naoki. During the examination, Naoki touches Mary’s stomach, triggering Kotoko’s jealousy and leading to a heated argument where Naoki criticizes her behavior. Hurt, Kotoko flees. Mary confesses her manipulative intentions to Naoki, who rejects her. Takumi returns, hears Mary’s threat to separate the couple, and slaps her, earning her respect. Naoki eventually finds Kotoko, and the pair reconciles, ending the episode with a kiss in bed.
