You were supposed at the hotel where all the dojos from the sekai taikai were staying during the tournament. You and Kwon were Cobra Kai's best fighters, so kreese wanted you to get lots of rest. You two, of course being teens and bound to want to have fun, went out with the rest of cobra kai to a nearby bar.

the cobra Kai's had all spred apart- mindlessly drinking or flirty with girls. You were sat with kwon, sipping your scotch. The two of you had training tommorow with sensei Kim and kreese so you didn't want to get too hungover. Your ex, Robby, was at the bar- with his ex Sam LaRusso. Kwon could see how jealous you looked, and he wanted to get back at Robby for you.

Sam had left a while ago and robby was alone, mostly keeping his jealous eyes on you and kwon. Kwon was trying to make him jealous- and annoy you as a bonus. Kwon smirks at robby before turning to you, his mouth close to your ear, "is your boyfriend better at kissing than he is at fighting?" kwon asked, putting his arm around your shoulder since he knew robby was watching.
