Shinobu Urakawa leads a double life. During office hours he is an unassuming, bespectacled employee who keeps his head down; at night he becomes a confident, attractive playboy who frequents Bar Caprice, a gay bar where he enjoys casual hookups. His careful separation between day and night is disrupted when Hikaru Omoteya, the handsome and arrogant star of the sales department known as the company prince, begins showing up at the same bar. Hikaru, though he identifies as straight, has come on a whim to test his appeal with men, and his persistent presence threatens Shinobu’s nightly sanctuary. Annoyed and wanting to reclaim his territory, Shinobu decides to seduce Hikaru as a form of revenge, betting that one night will be enough to satisfy his curiosity and send him packing. He confidently propositions Hikaru: “You’ve been waiting, right? For me to hit on you.”

What starts as a game of power and pleasure quickly deepens. Hikaru, inexperienced with men but unexpectedly responsive, finds himself drawn to the stranger he does not recognize as his despised coworker. Shinobu’s plan to love and leave falters as a single night stretches into many. The two navigate a secret affair, with Hikaru unaware of Shinobu’s daytime identity. As they spend more time together outside the bar—going on dates, visiting each other’s homes, dealing with everyday complications—their feelings shift from mere physical attraction to genuine affection. The story explores the tension between their public personas and private selves.

The narrative arcs include the initial cat-and-mouse seduction, the eventual revelation of Shinobu’s true identity to Hikaru, and the adjustment as they become official boyfriends. Later volumes introduce complications from their workplace: during a company trip, a photograph of them together in Hikaru’s room nearly exposes their secret, forcing Shinobu to risk revealing his true appearance to protect Hikaru’s reputation. This crisis deepens their commitment. Subsequently, Hikaru’s supportive supervisor Ousuke, who knows about the relationship, offers Hikaru a job at his new independent company and suggests the couple could live together, prompting discussions about their future and Hikaru’s fear of rushing things. Throughout, side characters such as the twin bartenders at Caprice, who appear in ever-changing costumes, and Hikaru’s friend and colleague Fuyuya add levity and support. The manga balances romantic comedy, explicit adult content, and emotional growth as two seemingly incompatible coworkers learn to trust and love each other. It continues to follow their evolving relationship and the challenges of merging their separate lives.
