Castiel, rare pairing longfics?

Do you know any good long fics where Castiel is paired with people other than Dean? (and I prefer no Castiel/Sam). It'd be great if the Winchesters were in the story, just not paired with Cas.

A specific J2 AU where they were in love as kids, forcibly separated, but find each other again

Hello again! I'm looking for a specific J2 fic that I read at least a couple of years ago, so it's not something posted recently.

J2 were friends as kids, and possibly soulmates?, but something separated them and when they meet again as adults, they don't recognize each other. The big thing is that Jensen thinks Jared is dead, and spends his time angsting over possibly falling in love with this other guy, when as far as he knows the love of his life died years ago. In addition, both of them go by different names in their adult lives, so they don't connect the dots right away. Jensen now goes by "Jack" as a way of leaving that part of his life behind, and Jared goes by JT (though it might be the other way around, and JT was his childhood nickname?) Jared also might've had amnesia; there's a lot I don't remember. Stuff happens, happy ending.

I'm pretty sure it's a stand-alone, or at least it was. So yes, if it was deleted and you have a copy, I would love one. But I'll also welcome recs with a similar theme of them being childhood sweethearts who are involuntary separated but end up together again.
