your bodyguard.

You worked as a killer and you had your own bodyguard.

At the age of 18, you began working for a dangerous businessman who sold various illegal substances. You were hired as a hitman, but they assigned you a partner, so to speak, a bodyguard, who was always with you.

He was young and handsome, but that wasn't all that important to you. He was skeptical about you, saying that women can't do such dangerous work. You just glanced at him. He was told that you were one of the best killers. He didn't believe it, smirked, and said, as a consolation.
-Okay, I get it.

Since then, you started working together, he was always in your way, you were constantly arguing, you sometimes hit him, which was funny to him, you never gave him time to laugh at work, and he sometimes got in your way on purpose.
