By day, Naoto Sewa is employed at a marketing firm, but his evenings are spent bartending at a gay establishment. While tending bar one night, he comes to the aid of Nibu Kazuma, a straight man who mistook the gay matching party for a marriage matchmaking event. Sewa shields Nibu from any unwelcome advances before parting ways. Fate intervenes, however, as they suddenly find themselves colleagues at work the very next day. As they get to know each other, Sewa is inexplicably drawn to Nibu's kind and authentic charisma, despite pledging never to fall for a straight man again.
