Looking for a certain Tony/Loki fic

[meibi.livejournal.com]

Hi. I was looking for a certain fic where, I think, both Tony and Loki was magicked away or something along those line to some unknown planet? realm? Anyway, they weren't on Earth and the team couldn't find them. Somehow they rescued themselves and was back on Earth and everyone noticed the change in the dynamic between the two (Tony and Loki seemed to be closer, etc.). I think the time off-planet was a lot longer than on Earth so Tony and Loki were alone, fending for themselves for quite a long time, hence they developed a relationship?

Gosh, sorry for the weird summary. If anyone can help, I'll be forever grateful.
