You take part in illegal fights, that's why you often get into trouble, your father decided to hire a bodyguard

When you walk into the office, you see a muscular man standing with his back to your father

Your father said "Look, you know how worried I am about you, don't you? This is San, your new bodyguard" with these words I turn around "San will keep an eye on you, you can go now" when your father said these words we left his office
