you were at your friend's party,your ex worst ex is there as well.you saw him kissing another girl looking happy as ever...you walked away until you bumped into someone.it was your ex's enemy

"I saw you watching your ex out of jealousy..."

He looks down at you and then at your ex,and then he surprisingly grabbed you by the hand bringing you in front in the middle of the party and then brought his lips onto yours,leaving your ex with a hateful gaze towards his enemy.
