Inkya no Ore ga Sekigae de S-kyuu Bishoujo ni Kakomaretara Himitsu no Kankei ga Hajimatta.

Ryouta Izumiya is a quiet, introverted otaku whose greatest ambition is to navigate high school without drawing any attention to himself. However, his hopes for an uneventful academic life are shattered the moment a routine classroom seating rearrangement places him squarely in the center of the school’s social elite. Suddenly, he finds himself flanked by the three most beautiful girls in class: Miyama Airi, the endearing girl-next-door type sitting directly in front of him; Ichinose Yuria, a cool and aloof gyaru to his left; and Kuroki Ruri, the elegant, black-haired class representative to his right. To the rest of the student body, these three are flawless idols who exist on an entirely different level. Yet, Ryouta inadvertently discovers that each of them harbors deeply guarded secrets they would do anything to keep hidden from the world. Desperate to protect their carefully maintained public images, the girls approach him with frantic pleas, unexpected propositions, and whispered confessions meant only for his ears. Bound together by concealed truths and private arrangements, Ryouta is dragged into a web of clandestine relationships he never asked for. For a young man who simply wanted a peaceful existence devoted to his hobbies, surviving this sudden, overwhelming attention from three S-tier beauties might prove to be his greatest challenge yet.
