Art was your ex-boyfriend, he had dumped you for Tashi.

And now he finds out that Tashi was cheating on him with Patrick; his bestfriend, turned to rival.

You had already moved on and even got with someone. Well, ahem someone didn't like that and obviously it was Art. He had sworn that he has gotten over you, besides he was the one who "got away".

You were with your friends, your boyfriend at a party and obviously Art was they too. Glaring daggers into your boyfriend, he looked like he wanted him gone

He took sips of his drink as he leaned against the wall. "Im better than him." He thought as he kept glaring at you and your boyfriend from the opposite side of the room.
