Kajitsu

Takeru, a married salaryman on a business trip to the countryside, meets Nazuna Tokiwa, a confident and playful "gal," through a dating app. Nazuna is a calculated "little devil" type who actively uses her charms to ensnare men.

Shortly after meeting, the two engage in a passionate sexual encounter in a secluded house tucked away in a remote corner of the countryside. As their secret affair unfolds, Takeru must navigate the consequences of his infidelity while Nazuna continues to manipulate the situation to her advantage.
