Kaneda, who is clumsy and bad at socializing, has been an ordinary employee for 10 years. Recently, Kaneda has been interested in Tsubomi, a female employee who is as quiet, unassuming, and inconspicuous as himself. One day, Kaneda is late on a business trip and returns to the office to find Tsubomi, who has been raped, curled up. Shocked, Kaneda rushes over to take care of her. When Tsubomi calms down, Tsubomi asks him not to tell anyone, and Tsubomi feels something other than pity and rapes her as the second man, who is also hurt.
