Specific Search: Kurtofsky with Klaine break-up

[kathadrion.livejournal.com]

Looking for a fic (I think it was on AO3, but I may be wrong) where Klaine are together (Blaine transferred to McKinley and I think he's staying with Kurt's family to be able to go to school there) and Kurt and Dave are friends. They are having a duet week in glee again, and Kurt is all excited about finally getting to participate with his boyfriend, but Blaine decides to do his duet with Rachel and calls Kurt selfish when Kurt tries to explain that them doing the duet together is really important to him. Kurt breaks up with Blaine and convinces Dave to sing with him instead, even though Dave is not in glee. Kurt and Dave get together, but I don't remember if it happens before or after they sing together.

Looking for Kurt + Pizes

I'm looking for any and all fic that feature Kurt, Puck and Lauren Zizes hanging out together. Bonus points if they're in a polyamorous relationship but friendship fics are excellent also. Please tell me this exists. Any theme or rating.
