The Arrowverse was a shared universe full of love.

Yes, sparks flew in the Arrowverse. It didn't matter if you were in Star City, Central City, National City, or even Gotham City. Heck, even the timestream had some romance as there were plenty of memorable love stories over on DC's Legends of Tomorrow.
