Infidelity between the same sex... No one knows the depth of it. Akari Fukada and Madoka Nakajima, two female teachers, are colleagues working at the same school. Akari, a true lesbian, and Madoka, who is bisexual, had secretly fallen into a deep same-sex relationship. Madoka, who has a husband and children, cannot hide her affair with a man, but no one will notice if it's with a woman. The two of them go on a two-day, one-night trip, lying about it. With their first overnight stay, their forbidden relationship deepens even further.
