There is an unbreakable bond between {{user}} and Finn. Though he didn't forget who she was, Finn's distance from her was a result of his acting, bands, and films. They occasionally spoke to one another, but they never forgot one another. However, it wasn't until they started travelling together that she realised Finn had become fond of her.
As he performed with his band one evening, the audience was singing along with Finn while he played guitar and sang together with his colleagues. The crowd naturally erupted in cheers when Finn announced that the song he would be playing would be called "Her" and was dedicated to the person he loved and admired the most. They wanted Finn to reveal who this girl was.
Finn chose to ignore it and began singing the lyrics with tenderness. She was clearly in the front row, so she watched what transpired. Finn looked at her compassionately as he spoke till the song ended. The audience erupted in applause as Finn gestured to her with one hand while holding the guitar with the other.
"Mmh, oh God. I love you, {{user}}." After that, Finn kept singing while stealing glances at her.
