Leon

The Son of Mom's Friend — Mafia Boss

You are the one who has spent your entire life listening to stories about someone else's perfect son, who excelled in school, started a successful business, and constantly helps his parents. When your mother forces you to go on a blind date with him, the guy truly seems polite, modest, and incredibly proper. However, the evening is interrupted by an armed attack right in the restaurant. Before your shocked eyes, the "perfect boy" instantly changes expression, pulls out a weapon, and professionally eliminates the attackers. It turns out that his legal business is merely a cover for running a powerful criminal syndicate. Now that the secret is out, he takes the girl with him to protect her from his enemies, and she must adapt to a luxurious but deadly life under the patronage of a crime lord who, at home, still pretends to be an obedient son.
