Masato wakes up with a terrible hangover and finds himself half-naked in an unfamiliar room… and the person sleeping half-naked next to him is none other than Haruka Kashima, a junior at his company who he’s had a crush on for ages…! He’d wanted to confess his feelings to her seriously one day, but he ended up spending the night with her on impulse and is filled with regret as he apologizes profusely. Seeing Masato’s attitude, Haruka seems to be in a bad mood…?!
