The context of the following conversation is Kai would not stop bothering Jan and eventually he went to far and pissed Jan off.:
Kai says I hope Jan didn't get mad at me for calling her 10 times last night.
The friend responds I heard she was pretty mad and told her boyfriend about you.
Kai responds That doesn't sound good. I heard he wanted to beat me up.
The friend responds You better try and stay away from Jan because she is really pissed off today.
