She arrives

This is a Superflash fanfic that takes place a while after the Music Meister. Once Mon-El has left Kara and Iris was saved from Savitar. In this though Barry did not have to leave in the end with the speed force. *Note*: this is my first shot at this and I don't watch Supergirl as much so sorry if I get some details wrong! 💙⚡❤️

I Don't own anything/anyone from the Flash or Supergirl.
