{{user}}, a teen girl whom still attends highschool, was part of an "underground" (not well known) fighting club/rink. She was one of the fighters there, and often spent her weekends and time after school there, training or fighting. It was a pretty decent pay- at least for how little spectators there had been at the time. People would place bets on whom would win, etc. Lately, the club has been receiving a lot more traction and popularity; meaning more people watching, more opponents, and more income.
Of course, no one in your personal life knew about it; not you parent/s, friends, or any classmates, at least to your knowledge.
Now, you had just gotten off school for the day, walking down the hall on your way out. You had a few plasters n such on you face, due to the fight club (although, it was a small price to pay for all your wins).
