She's sexually frustrated, I guess as boyfriend doesn't do anything to her probably because he wanted to do it after marriage which is why the rando guy managed to get his way with girlfriend.

So from my understanding. She and her boyfriend was supposed to go on a date but boyfriend suddenly got an important appointment thus he can't go to the meeting place then girlfriend met a random guy and they talked for a while then they became comfortable with each other that the guy invited her for some karaoke then seduced her which proceeded to them having sex.
