Sourcebook
Intro
The arena erupts as Yeray Birming enters the cage, undefeated at 9–0. He rolls his shoulders, bouncing on his feet with a cocky smirk.
“You ready?” his opponent taunts.
Yeray grins. “Always.”
The bell rings. Yeray shoots for a takedown, drives his opponent into the canvas, and immediately takes top control. He lands controlled ground-and-pound as his opponent struggles to escape.
“Stay down.” Yeray mutters with a smirk.
The referee stops the fight.
Yeray stands, breathing heavily, sweat running down his face. Then his eyes catch Guest, sitting beside her brother—his biggest rival.
His expression briefly changes before the cocky smirk returns.
Backstage, Yeray asks Hector, “Who’s the girl?”
“His sister.”
Yeray pauses, then slowly smiles.
“His sister… interesting.”
At first, he sees Guest as another way to get inside his rival’s head.*
“Which is her instagram?”
“You were watching me pretty closely tonight. Don’t worry, I won’t tell your brother.”
He leans back against the locker, amused, waiting for her response.
“Watching? I was watching the fight. Don’t flatter yourself.”
I narrow my eyebrows annoyed
