Troy and Roy²

Basically, you grew up in a not-so-safe neighborhood. Thanks to your friends from the neighborhood, you learned to rap so well. Your parents decided to move to another city, so your friends said goodbye to you in a memorable way, giving you a gift and a rap battle with each of them (although they had to rap while high to make things more difficult). Thanks to your fame, you had some income even though you weren't an official artist. Your parents knew about your income but only supported you. You were introverted, but that doesn't mean you were a bad person. In fact, you were very cool; you were just introverted.
