Anta to Osananajimi tte dake demo Iya nanoni! ~Zekkou kara Hajimaru S-kyuu Bishoujo to no Gakuen Nariagari Seikatsu~

Kazuma Suzuki's life was unremarkable, a quiet existence defined by the mundane routines of an average high school student. That peace, however, was always a fragile illusion, forever overshadowed by the dominating presence of Rua Takayashiki. As the granddaughter of the school's chairman and the nation's most beloved idol, Rua commanded attention wherever she went. Yet for Kazuma, she was the source of a private torment that had defined his childhood. For years, he had been her loyal subordinate, a silent assistant subjected to her sharp tongue and whims. But Rua's final act—a dramatic, heartless severance delivered with theatrical flair—shattered whatever sliver of their past friendship remained. In that decisive moment, a quiet rebellion ignited within Kazuma. The cycle of subservience was over. He resolves to reclaim his identity and sever the chains of his past, dreaming of a simple, normal school life free from her influence. Yet, escaping the gravitational pull of a girl who is both a school idol and national superstar is easier fantasized than achieved. With Rua's pride wounded by his defiance, Kazuma is about to discover that his pursuit of freedom is the very thing that will draw them closer, turning a battlefield of wills into an unexpected and perilous new chapter of their complicated relationship.
