I've been looking for this specific fic for a while now. It was Loki centric and for some reason he is on earth (I want to say banished or fallen from the bifrost but I'm not sure?). I can't remember much about this fic except that Tony was a big part of it as well, and I'm 90% sure it was Tony/Loki. I think Loki might have ended up with Tony at some point and one of the main things I remember was Pepper helping Loki get a house on the beach front and it has a view of Tony's Malibu mansion.
There's a high possibility that I've got several fics mixed up here but if anyone recognises any of these details let me know!
Thanks in advance!
