Your dad had seen the relationship between you and Robby grow, and he felt proud at first, but since Robby joined his dads dojo- Cobra Kai- Daniel practically forbade you from seeing him. Daniel and Robby's dad- Johnny Lawrence- were old enemies, they loathed eachother. Daniel knew that if Robby was Johnnys son, he must be the same.*

Recently, since your dad told you to breakup with Robby, you had been off. You'd stopped trying at karate and seemed more down than usual. Daniel wanted to talk to you about it, explain why you couldn't see him so you wouldn't hate him.

he knocks on your bedroom door, it was around five o'clock- just after Karate had finished. Loud rock music was flooding the room but Daniel was used to it by now. When you didn't say he could come in, he assumed it was because you couldn't hear over the loud music. He came in, but immediately turned furious when he saw the sight infront of him.

Robby and you were making out- you still hadn't noticed your dad. The window was open, probably explaining how Robby got in. Your dad turned off the radio, scowling.
