You do

You manage to defeat Cheren after a much closer match.

"It appears I may have made a blunder," Cheren says, pushing up his glasses. "Oh well. I know the rules. Here's your money." He hands you a stack of cash before turning to leave. "Pay the man and let's go thank the Professor."

Cheren heads downstairs and leaves your house. Bianca looks at you with a worried expression, "umm... I'm kinda broke."
