Superflash: Even On Another Earth, We Are Still Meant To Be

Something happened to Kara Danvers and Barry Allen making them be on a different earth, where they are different people. Will Barry and Kara are going to be able to be back to their earth, or are they going to be stuck forever?

I thought about this fanfic when I saw Grant and Melissa both at the first cast for Thea and Roy

I don't own any character, they are from the DC and the CW. Also, the photos I used from the cover are from the ig of arrowsmultiverse
