Doutei Otaku to no Sex ga Ii Hazu ga Nai

Makoto Mitsuya, an economics student residing in a dormitory, finds himself enjoying total freedom to indulge in his otaku hobbies after his original roommate is hospitalized. However, his peaceful solitude is abruptly disrupted when a new roommate moves in: Ken Hayami. Hayami is the polar opposite of Makoto—a flashy, energetic party animal with a vastly different lifestyle and appearance. Initially, Makoto harbors resentment due to their clashing personalities and Hayami's bothersome antics, but he slowly begins to lower his guard as Hayami persistently attempts to bridge the gap between them. The dynamic shifts dramatically one evening while the two are drinking together. When Hayami playfully teases Makoto about being an inexperienced virgin, Makoto reacts in a moment of annoyed impulsivity and pushes him down. To Makoto's surprise, Hayami responds with unmistakable pleasure, causing Makoto to get carried away in the heat of the moment. Driven by the unexpected turn of events, the two cross a boundary and end up engaging in an intimate physical encounter.
