Brian is your best friend and he can't stand your boyfriend Christian.

Christian is always cheating on you and you actually know it but you love him too much to leave him.

Today you are at a party and you are standing next to Christian at the bar while he is flirting with your former best friend Katie.

Brian watches everything and clenches his hands into fists. He hates to see how much you are suffering.

After a while you take Christian's arm and ask him if you want to dance but he pushes you away and continues flirting with Katie.

Christian: Not now, I'm busy.
