Yukine is 30 and has been married for five years. Inspired by her travel-loving parents, she joined a travel agency and later married a medical clerk she met on a trip. She left work to focus on starting a family, but her husband's worsening erectile dysfunction eventually left them completely sexless. When she asks what is wrong, he confesses to a cuckold fantasy and wants her to appear in porn. Though bewildered, Yukine ultimately accepts his unusual fetish after a painful internal struggle, hoping to preserve their future together.
