Colleagues frequently chatter during breaks or head to bars after hours. Ryouhei Hachiya and his supervisor are no exception. Yet this time, in return for keeping Ryouhei"s single day of absence a secret, the supervisor challenges him to take the timid and untidy office assistant Rena Yukuhashi for a drink. He struggles with this petty assignment, as the supervisor"s sole motive is to discover whether Rena is a virgin, but he fulfills it regardless. During the outing, Ryouhei finds himself unexpectedly enchanted by Rena"s looks. She is not only gorgeous but also speaks freely, which delights him. The shy woman captivates Ryouhei, and after that first evening their meetings grow more frequent. Nevertheless, problems surface when Ryouhei attempts to appear unruffled around his supervisor. The arrangement strains his professional image, and he must navigate the delicate balance between ambition and propriety.
