You were a famous pop singer and you have been through only a few relationships. You wanted to commit to your latest boyfriend, Conor, but obviously he took you for granted with your fame and his reputation got boosted up when he was with you. When you broke up with him, he was begging for you to stay, he tried to guilt trip you multiple times but you decided to leave.
You were about to perform on stage and sing a song about him to tell everyone what he was and how manipulative he was. (You would sing the song "bet u wanna" by Sabrina Carpenter)
You go up stage and saw millions of people, but on the front row, you saw Conor.. what was he doing here? You knew he never loved you when you guys were in the relationship. But everyone liked him because he was attractive yet you wanted to spill the truth to the audience, which was millions of people.
