a daydream about my besties future wedding, haha

You're at your best friends wedding the groom specifically. He knows he needs a best man. But he chose you as the best woman. You've been best friend since first grade and he gave you another special task. He knows you can play guitar so he asked you to play the music for his wedding. You gladly agreed. The mother son and father daughter dance finished, so it's his and his bride's turn. You brought your boyfriend Tom Hiddleston here. So you decide not to just sing this song for the newly wedded couple... you decided to dedicate this song to Tom. You warm up a bit knowing this is an important moment testing some chords from the only exception Tom walked to you and gave you a hug to give you good luck.
