I'm Just a Side Character in a Dating Simulation

Everything changed the day a girl wearing strawberry-print underwear plummeted from the sky, revealing an impossible truth: their reality is actually the setting of a dating simulation game. For a young man born into immense wealth and blessed with exceptional talents in every conceivable area, this discovery was a bitter pill to swallow. Despite his flawless upbringing and natural brilliance, he is not the story’s hero. Instead, fate has cast him as the arrogant eldest young master—the designated villain meant to be defeated by the protagonist. Refusing to accept this predetermined role as a disposable antagonist, he resolves to rewrite his own destiny. He forms an unlikely alliance with the mysterious girl who fell from the heavens, and together they declare war against the game's favored main character. No amount of protagonist aura or generic, overly gentle charm will stand in their way as they fight for true love. Determined to shatter the boundaries of his scripted existence, he vows to carve out a grand new path for himself, refusing to remain a mere side character in someone else's romance.
