- Description from novelbuddy

Waking up in an unfamiliar world with no memories, I had only one advantage—a mind filled with knowledge of fictional tropes, clichés, and common sense learned from countless novels.At first, I thought I was trapped in a romcom nightmare when I started triggering events like “Helping a Girl on a Rainy Day”, “Damsel in Distress”, and “Tripping Into the Heroine’s Arms.” Naturally, I shut those nonsense down before they could escalate. No forced romances. No misunderstandings. No cringe.But something was clearly off.The world wasn’t just a slice-of-life comedy.Beneath the cliché academy setting, there were whispers of awakening powers, hidden dangers, and a brutal magic academy entrance exam.And every challenge I prevented or manipulated was an opportunity to grow stronger.[Title Earned: Background Character.][Achievement Unlocked: Firm Mind.][New Skill Acquired: Background Character's Aura.][New Ability Acquired: Anti-Narrative Influence.]I may be just a background character, but if fate insists on throwing these events at me, I’ll turn them into stepping stones.Let the protagonists play their scripted roles—I have my own path to power.
