Kanon Kanade, who secretly harbors feelings for her department chief, ends up on a business trip with him. Due to a hotel mix-up, they're forced to share a twin room, and Kanon seizes the opportunity to grow closer. She tries various tactics—sitting suggestively close, pretending to be drunk so he'll let her rest her head on his lap, mustering the courage to confess "I like you," and suddenly kissing him out of nowhere—her actions growing bolder by the minute. She announces they'll go to the bath together, declaring, "I'll wash your back for you," and when he still resists, she pleads in a cutesy voice, "You can keep loving your wife...," yet her feelings refuse to be held back.
