Seeking Correct Tag - B/J together but Gang unaware/don't know

[netlagd.livejournal.com]

I'm looking for fics in which Brian and Justin are together but the gang is either unaware of it or don't know.

These may be fics like sian265 and sydneyalexis's The Mask where Brian meets Justin away from Pittsburgh and has a relationship with him and the gang don't know who Justin is.

or a post 513 fic where they are B/J are still together but the gang either is unaware of it or don't give it credence.

I guess the tag would be "Secret Relationship" but are there any other tags?

Oh, and I guess I'm looking for secretly married as well.

Oh, and written in the third person please - not overly picky, am I?

ETA: Several good recommendations on fics in comments - no real advice on Tags

There's actually quite a couple of them...let me see...

It Happened When

Betrayal
http://www.fanfiction.net/s/5989500/1/Betrayal

and its sequels
Ambush
http://www.fanfiction.net/s/6089825/1/Ambush

Retribution
http://www.fanfiction.net/s/6093409/1/Retribution

Restoration
http://www.fanfiction.net/s/6098269/1/Restoration

They are all very anti-michael though so bear that in mind.

Betrayal, Ambush, Retribution, and Restoration have (apparently) been taken down on ff.net. Since the author is not identified, it makes it difficult to find the stories elsewhere. However. There is a series by JulesMonster on AO3, named Perfidy, comprising the same four titles. And it's anti-Michael, so I believe it's the same. https://archiveofourown.org/series/26451
