Polaroid (Gracie Abrams)

"I never was looking for you, you came out of the blue. And now i am cursed to look for you for the rest of my life. I'm truly still in love with you, even now. Every song i ever wrote and will write is about you. And i hope you know, whenever you are ready and if you want, i want to try again." I said to her, in front of dozens of cameras and hundreds of fans. Yet, my eyes never left hers, she was on the VIP tent with my sister. I didn't know she was gonna be here tonight, our biggest gig yet. She was looking as beautiful as ever. I never have seen anyone as beautiful as her. She didn't stop looking at me, even after i stopped talking. We kept the eye contact. And then she send me a kiss. A small gesture that sparked the fire inside of me.
"I love you. This is Polaroid, the first song i ever wrote about you. " I said on the microphone and started strumming my guitar. She nodded, still looking at me, and my sister put her hand around her, keeping her close.

But how did we even get here?
