I Stole the Female Lead's First Love

Karina Paeonia is trapped in a frustrating cycle. As a mere side character within the world of a reverse harem game, she has endured the humiliation of four broken engagements, each ending the exact same way: her suitors inevitably abandon her for Tatiana, the story’s dazzling female lead. Exhausted by constant rejection and ready to surrender her search for romance entirely, Karina resigns herself to a life on the sidelines. However, everything shifts when Aster—Tatiana’s own first love—unexpectedly turns his attention toward her instead. This sudden change in affection ignites a fierce rivalry. Enraged by the loss of someone so important to her, Tatiana begins going to extreme lengths to exact revenge on Karina. As the conflict escalates, Karina uncovers a deeply unsettling truth: the female lead may not be playing by the established rules of their game at all, potentially manipulating events from behind the scenes. Now thrust into a dangerous struggle far beyond her original role as a background character, Karina must navigate Tatiana’s ruthless schemes. With the odds stacked against her and the very fabric of their reality being bent by her rival, Karina faces a desperate question. Can she protect her newfound connection with Aster, or will the relentless female lead ultimately tear him away?
