Despite Misaki Hinase and Souichi Hino's undeniable chemistry, all they do is clash and bicker, be it at work or on a relaxing night out with their colleagues. When the two coworkers wake up naked next to each other in a hotel room, they deny any recollection of what transpired. However, that one night spent together messes with Hinase's head, and she begins to notice subtle and more intimate changes in Hino's behavior. Although they wish to continue pretending, their true desires and intentions become increasingly difficult to hide.
