Mikako decided to move to Hokkaido due to her husband's work. She says that her best friend, Junko, will give her a farewell party, so she decides to stay at her house. While she was enjoying talking about old stories, Junko's son, Naoto, came home and had a good time together. Naoto, fascinated by Mikako's adult charm, sees Mikako taking off her clothes in her dressing room that night to take a bath. Mikako, who noticed her gaze, began to gently seduce her in her usual beige underwear, even though she was drunk with alcohol.
