Boku no Bungeibu ni Bitch ga Iru nante Arienai.

Ikuno Kousuke lives by a simple, cynical philosophy: truly beautiful girls are almost always trouble. Guided by this belief, he has spent his high school days quietly retreating to the literature clubroom, dedicating himself entirely to a peaceful otaku lifestyle. However, his comfortable routine is abruptly shattered when Shinonome Ibuki, a stunning beauty who serves as the student council president’s assistant, delivers an ultimatum. To prevent the impending dissolution of his beloved club, Kousuke is forced to act as a consultant for the student council alongside Ibuki. Their very first assignment involves Aizawa Mahana, a blonde, well-endowed beauty whose popularity rivals even Ibuki’s own. While campus rumors paint Mahana as a promiscuous girl who dates countless boys, the truth is far more innocent—she has absolutely no romantic experience whatsoever. Desperate to dispel the gossip, she approaches Kousuke with an outrageous request: she wants him to act as her fake boyfriend. Thrust into a chaotic web of misunderstandings and unexpected romance, this unlikely pair sparks a hilarious love comedy where a dedicated otaku finds himself entangled with the school's most notorious "bitch."
