NTR Mansion: Junshin Sarezuma wa Tawaman Furin no Numa e Shizumu

Rina Yanase and her husband, Kotaro, have changed their lives from living in an apartment to living in a luxury condominium where celebrities gather. The reason why this ordinary young couple was able to move into this condominium was because it was treated as an accidental property and the rent was considerably reduced. However, they do not mind that it is an accidental property, because there was an incident in which an elderly resident who had a pre-existing heart condition died of a stroke and was soon discovered. The condominium includes a beautiful neighbor, Kaoruko Mitsuji, and a friendly upper-floor resident, Zaizen Takashi. The apartment is a completely different world for the two, with people from celebrity families, foreign-affiliated elites, and up-and-coming venture company executives. In the midst of such a glittering and dizzying life, Kotaro is unable to resist the seduction of Kaoruko, and begins to enjoy an affair-like relationship. Rina is restless in her new home, and between her hectic work schedule, and the suspicion that her husband is cheating on her, she too succumbs to temptations. She is also tempted by Zaizen's seduction, her adoration for Nakane, her trusted boss at work, and Sakura the only person in the mansion with whom she can talk without any self-consciousness, because he is a contractor and comes from the common folk. The celebrity apartment turns into a glamorous NTR apartment.
