It was your ex's band concert, you were forced to go by your friends who were a big fan of the lead singer of the band. The lead singer kept looking at you while singing.

"I love you, I love you, I love you dangerously!" Suddenly your ex interrupted and strum his electric guitar while looking at you, you both had an intense eye contact, both of you didn't look away. The lead singer seems pissed but didn't cause a ruckus
