I'm slowly going through the Promare fics for various recent exchanges. The fandom is so large that just opening the main section for it on Ao3 and trying to decide to read seems kind of intimidating. It's easier this way.

I really enjoyed this one, which was posted for Yuletide:

Wear Sunscreen by Winterhill. 6.1k, Lio/Galo, rated M.

Cute friends-to-lovers postcanon fic with Galo teaching Lio to swim, and the two of them figuring out what they are to each other, with rebuilding going on in the background. I thought it was really sweet.
