Favorite Crackships and Rarepairs?

It's Valentine's Day, and one of my favorite aspects of shipping culture is crackships and rare pairs. If you can find a point of common ground and an interesting dynamic between two characters, you can get people invested in something they never thought was possible. What are some of your favorites?

My major hyper fixation recently is the ship between Kay Faraday and Eustace Winner/Sebastian Debeste from Ace Attorney (though I will cosign any argument that Kay is probably a lesbian). Their shared trauma surrounding their fathers and how they handle their grief would make for some really interesting interactions I think, and I think Kay is the perfect person to give Eustace a confidence boost.
