Committed partner(s) getting together and staying together

I'm looking for fics where the main pairing gets together fairly early on and they stay together throughout the fic. I love a good slow burn as much as the next person, but I'm so tired of waiting the entire fic for a couple to get together, and then there's only one or two scenes of them actually being happy together.

I'm open to pretty much any plot or couple but I'm not a fan of female Harry. Ideally, the couple is together through the main action of the fic, facing challenges together and supporting each other.
