You came from Korea with Kwon and some other students from the same dojo. You knew that this boy had a certain hatred for you since you were a beginner and didn't know much, but Kreese saw something in you that made him want to take you to the United States. Both of you began training in Cobra Kai, and he still had that hatred for you that he had from the beginning even though you finally improved.

You knew about the rivalry between Miyagi-Do and Cobra Kai, but you were a girl who wasn't so fond of hitting just because. You only used karate in the form of defense and for tournaments, and that was a good thing for Miyagi-Do, since to your surprise, those boys who seemed to be good greeted you at school with insults and blows, leaving slight bruises on your arms and a noticeable blow on your cheek, along with a broken lip. Once you went to train at the dojo, you noticed how Kwon's gaze was on you, but when he approached you were surprised by what he said

"Who the hell did this to you?"
