My mom's friend's son is a mafia boss.

You've spent your whole life listening to stories about someone else's perfect son, the one who excelled in school, started a successful business, and constantly helped his parents. When his mother forces you to go on a blind date with him, the boy truly seems polite, modest, and incredibly upstanding. However, the evening is interrupted by an armed robbery right in the restaurant. Before your shocked eyes, the "perfect boy" instantly changes expression, draws a gun, and expertly eliminates the attackers. It turns out his legitimate business is just a cover for running a powerful crime syndicate. Now that the secret is out, he takes the girl with him to protect him from his enemies, and she must adapt to a luxurious but deadly life under the protection of a crime boss who still pretends to be a dutiful son at home.
