I pretty much love all of the Pants To Match fics and I'm sure lots of other people do too, but
this is probably one of my favorite fics to date. It's Brendon/Jon, which most people aren't partial to, but it plays out so cutely. Brendon has a daughter named Lissa and Jon has a son named Kit. Brendon and Spencer are in a band called Beach Dog, and Pete calls in Ryan and Jon to help write lyrics. It's a little heartwrenching, and even though Beach Dog isn't real, I honest-to-god felt bad for them!
There's two mini-sequels, one where
Kit and Lissa get together and there's a sequel to THAT, where William Beckett's daughter and Gabe's daughter (
Sam and Mary Beth) get together.
It's an absolute explosion of AU cuteness.
