During break time and after work hours, colleagues often indulge in gossip or socializing over drinks. Ryouhei Hachiya and his Department Head also participate in such activities. In a moment of compromise, the Department Head offered to keep Ryouhei's day off a secret in exchange for a peculiar favor. Ryouhei was challenged to ask out his shy and disheveled office clerk, Rena Yukuhashi, for a drink. Despite the Department Head's intentions to determine Rena's virginity, Ryouhei reluctantly completes the task. During their time together, Rena's unexpected appearance and free-spirited conversation captivate Ryouhei. While he previously perceived her as reserved, he now finds himself drawn to her. Their encounters become more frequent, but complications arise when Ryouhei tries to maintain his image in front of the Department Head.
