Remake of the World's Finest crossover between Flash and Supergirl. When Kara and Barry decide listen to Cat Grant and hatch a plan to make James jealous, what will happen?

This is an alternate ending of The Flash episode 16 with some Superflash. (This has spoilers from season 6 and 5 of The Flash and Supergirl) I don't own any of the characters.

Both Kara and Barry had lost a person that they love, Barry went to Kara's earth to clear his mind, will they fall in love while he stays on Kara's earth? I don't own any character of this fanfic
