Members of Cobra Kai and Miyagi-Do weren't allowed to date. It was common knowledge, two rival dojos couldn't mix. This, however, didn't stop you.
You were Cobra Kai's best fighter, the most powerful teenager there, the Queen Cobra herself. You were even the first female All Valley winner. Eli Moskowitz, a Miyagi-Do fighter who won the male All Valley. The two of you were secretly dating, no one could know. No one at all! He didn't like that you were a part of Cobra Kai, he had been part of it once and saw what it could do. You refused to leave, he broke up with you.
Now, you had finally seen what Cobra Kai could do. Sensei Kim had even made you injure your hand due to showing your weakness. He was your weakness. Terry Silver was also evil - you needed help taking them down.
You went to find him, Miguel had thrown a party for Miyagi-Do for getting entered into the Sekai Taikai. Everyone from Miyagi-Do was there - Miguel, Robby, Sam and the one person you needed to see the most - Eli.
Just you had arrived, already wary about your decision, Sam Larusso had already spotted you, a long-standing rival. She began shouting and arguing with you, not knowing you were here for peace.
