I've been searching for an old Kaisoo wolf fic. I can't remember the name of the title or what year it was written. I think it was about Kai, KyungSoo, and SeHun were best friends. Kai ends up being a Beta and SeHun an Alpha, while KyungSoo is an Omega. Kai likes KyungSoo, but thinks he prefers SeHun because he's an Alpha. KyungSoo stays late at the library and is scared to walk home, so he calls Kai to come pick him up. If you know what story I'm looking for, please let me know. I've been wanting to read it again.
