Jared/Jensen
+ The Waiting Game by 
dugindeep
Jensen has been in love with his best friend for a year now, which makes pretending to be boyfriends at Jared's birthday party pretty intolerable.
Fake!boyfriends tropes are always a faaaaaave.
Derek/Stiles
- Living With Lycanthropy by WhoNatural
AKA: The Sterek Rival Bakeries AU
Wherein they both own bakeries, Stiles tries not to run his grandmother's legacy into the ground, Laura wants to be a better alpha, and Derek can't seem to get Stiles' attention the regular way - so naturally, he accidentally initiates a prank war. (Or, if Teen Wolf was more like Gilmore Girls, with everyone far too invested in whether the Hale boy and the Sheriff's kid will work it out, and Laura Hale wrote a handbook for alpha werewolves.)
Oh man, this was SO CUTE. I love Idiot!boys that make things worse before better and yeah, awesome.
- Losers by sitlinskisparkles
Where Derek is new to college, eager to spend his time learning, and Stiles is everything he didn't want in a room mate. He's loud, he's into sports, and he keeps trying to make Derek do things.
Or, the one where Derek falls for a jock, Erica will cut you if you disturb her studying, and Jackson is a closeted romantic who pretends to hate everything.
Oh man, this was ADORABLE. Again, idiot boys being idiots. This AU was adorbs.
- Bumped Into You Somehow (I Break Into A Thousand Pieces Over You) by HollowIsTheWorld
The one where Derek is infatuated with the barista who works at the cafe in his building - only to end up with the young man as the company's new tech intern. Brilliant, obnoxious, and far too attractive to be fair.
Sigh, coffeeshop AUs are also a fave. Basically, AU's ftw.
- Stilinski's Home for Wayward Wolves by owlpostagain
“At least your puppies knock first,” Stiles snorts. “Here I thought their alpha raised them to be well-mannered.”
“There’s a sign,” Derek responds stiffly. Stiles, whose curiosity outweighs even his hardest of grudges, abandons his chilly façade of nonchalance in a heartbeat. He jumps right up and all but pushes Derek out of the way in his effort to get to the window, and sure enough when he leans outside there’s a laminated strip of cardstock duct taped to the vinyl siding: DON’T FORGET TO KNOCK Stiles gets cranky when we scare him
---
Or, in which Stiles Stilinski moves to Beacon Hills for his junior year of high school and accidentally adopts a pack of teenage werewolves.
I love the banter that's filled in this as well as the full on characterization of Stiles. He's lovely in this <3
