Frustrated by their clashing personalities and Hayami’s annoying behavior, Mitsuya initially held a grudge, but slowly begins to open up thanks to Hayami’s attempts to get closer. One night while drinking together, Hayami teases Mitsuya for being an inexperienced virgin. Annoyed by the teasing, Mitsuya impulsively pushes him down. But when Hayami reacts with obvious pleasure, Mitsuya gets carried away—and the two end up having sex…!?!? Note: Includes one extra chapter.
