Kurt centric fic recs where ND is rude

[snakesalike.livejournal.com]

Hey, I'm looking for some fics where Kurt is dating someone (could be badboy!Blaine/canon Blaine or Sebastian, or maybe sebklaine) and ND overreact and are trying to be controlling and just don't approve.

That is my first choice plot wise, but if you know of some fics where Kurt gets tired of Mercedes' crap and tells her off or something that would be good too.

Basically, I just want Kurt or his bf (or both) telling some people off.

Thank you, in advance. :)
