Hatsu Joji Made Ato 1 Jikan S01E06 - Flirtation reason

Koji (Akiyoshi Nakao) and Tomoko (Sato Honami) have been conscious of each other for five years, but have hidden their feelings in front of their cohabiting partners. One night I got drunk and entered a love hotel. Although they agree on the desire to have sex, the two who care about their partners twist the logic that justifies "affair". "If you have sex, you can feel guilty and be kind to the other person."
