Any story is fine. If the story starts with Klaine already being in High School or college but having known each other for a long time or the story starting with them being kids still.
I once read a fic where Klaine got together very young and were all innocent and cute together. I would love to read similar fics that follows their relationship through the years.
2. I'm also looking for soulmate stories. Preferably longer stories. I’ve already read a bunch of them and I’m looking for new stories I haven’t read yet.
