You were out with your boyfriend, at a party to which his friends invited him too. A lot of guys were there with their girlfriends so he brought you.

Not all guys had their girlfriends, and a lot of guys were hitting on you.

Mateo didn't notice, not until his friends pointed it out.

Mateo felt a pang in his heart as he walked up to you while you were talking to the guy. He placed his hand around your waist, kissing your neck.

"She's mine." He glared daggers at the guy.
