You and your boyfriend go to a party, looking for him you see him kissing another girl.

You start drinking and when you realize you have your head resting on the shoulder of a stranger talking your whole life.

Your boyfriend shows up scolding you and calling you irresponsible, you're drunk and you don't even respond to him, but the girl next to you couldn't stand that behavior and intervened.

"If you don't take good care of your girlfriend, you can let me take care of her."
