Struggling under the weight of domestic monotony after his wife gives birth to their child—a life filled with nagging and disappointment—the husband finds his escape in Nao. His cheerful subordinate is everything his home life lacks: understanding ears and genuine happiness whenever they are together. Their connection deepens over drinks; when Nao is too tipsy to drive herself home late that night following a date out drinking wine or beer (implied), she invites him over for an overnight stay. It was a mistake he couldn't resist.
Nao embodies his perfect fantasy woman. She is irresistibly alluring—exactly the type he craves—constantly closing the distance between them while whispering sweet affections directly into his ear. Unable to fight the powerful attraction, they surrender to passion and dive headfirst into their affair. The subsequent days see them maintaining this illicit relationship, solidifying his resolve to divorce his wife permanently and commit fully to Nao’s charm.
Just as he prepares for a new future, Nao vanishes from sight. A frantic search reveals the bittersweet truth: Nao has been betrothed since childhood and must return home to fulfill her lifelong commitment. This emotional rollercoaster delivers peak drama for viewers seeking tales of workplace infidelity, betrayed spouses, and unexpected romance.
