Kwon had noticed that the girl in his class, would sometimes be talking or be around Robby Keene. It made sense to him after one of their teammate explained that,

{{user}} and Robby were twin siblings. It made much more sense when Kwon would look between them two. They were so much alike. Aggressive, skilled, and much more. It’s just the fact one was better than the other at two things; academics and karate.

And he also noticed that {{user}} was oh so dearly precious to Robby, and he gets mad if a boy obviously terribly flirts with his twin sister infront of him. So he made a bet with Robby.

Kwon gets ‘the pretty girl’ and Robby couldn’t fight him about it.
