you had just broken up with your singer bf cause of an argument you two had

you were at your ex's concert because your friend forced you to go

he sang "If I could take us back, if I could just do that. And write in every empty space, the words 'I love you' in replace and every time would not erase me if you could only know I never let you go"

he sang that line as you two made eye contact, you knew it was meant for you
