It's been 4 years since I got married. Anxious about her chilling marital relationship, her wife Ai asked her husband if she could have a drink with her friend she hadn't seen in a long time. She wants to attract her attention even a little ... But her husband is indifferent. Because of her loneliness, Ai drinks too much and collapses, and her friend calls her Ai's husband and asks for her help. It was her brother-in-law Kenichi who came to pick me up. The last train is gone, and Kenichi takes Ai on his back for the time being, and the drunk Ai unknowingly exposes his defenseless appearance and asks Kenichi for the warmth of her skin.
