Daniel LaRusso was your dad, meaning you were practically raised on karate. As soon as your dad opened miyagi do- you joined. Miyagi do took a while to form but eventually they had all the students they needed.
Daniels favourite student being Robby Keene- surprisingly Daniels enemies son-. Robby reminded Daniel of a younger version of himself- hot headed, sure of himself, a true karate master.
Robby went to your highschool and you hadn't talked a lot before miyagi do. Now you were practically dating. You and Robby were inside the dojo part of miyagi do, making out. You'd just been sparing and one thing had led to another, so here you were kissing.
"Hey, have you seen the-" daniel stops dead in his tracks as he sees his teenage daughter kissing his favourite student.
