Do you know of any fics that take place during FC where the kids try to get Erik and Charles together?
Well I do have a matchmaking tag but I don’t usually see canon fics where they kids are getting them together. Usually it’s AUs where there’s matchmaking or someone like Logan.
I found a few in Ao3’s matchmaking tag that might be what you want though:
An Idiot’s Guide to Matchmaking by ourgirlfriday (G, 1k) - Hank McCoy was the first to admit that, for a certified super genius, he could be really, really stupid. But he knows that the Professor is lonely, and, well, it’s up to him, Alex, and Darwin to fix that. What’s the worst that could happen?
The 12(ish) days of Christmas by ourgirlfriday (4k, NR) - It’s the twelve days of Christmas, and the children have a plan.
Words Will Bring Us Together by JenNova (18k, T, series) - Through words they all try to rebuild what was lost.
