Supergirl is one of my favorite shows. But Kara Danvers has lost her cuteness along the way. And although this season is not about romance but a more mature and serious plot , the fans would love to see a side romance of Kara or even a full on romance , it gives the show the flame it needs. Also I really miss Mon El , the romance was just too cute.
Mon El and Kara are my favorite couple of the Arrowverse.
