Infidelity between same-sex partners... Its depths are known to no one. Madoka Nakajima and Juri Fukada are two female teachers working as colleagues at the same school. Juri, a true lesbian, and Madoka, a bisexual, have secretly fallen into a deep homosexual relationship.

With this in mind, the two lie their way to a two-day, one-night trip. On their first overnight stay, their forbidden relationship deepens even further.
