I have this fic stuck on my mind. it's an wolf!au fic. the story goes like... Kyungsoo was being abused(i think) by his father, and then one night he was sold to someone he didn't know. that someone was a wolf and he was being abused by the pack of wolves. and was bitten and changed unwillingly as a wolf. then one day the pack was attacked and Kyungsoo was saved by Yunho and BoA. but unfortunately wolves need only one omega per pack and Yunho's pack has already BoA. they turn Kyungsoo to Kris' pack to be their omega. at first Kyungsoo was afraid that everyone will hurt him like in the past. then everyone take turns so that Kyungsoo will open up with them. As an omega everyone needs him to give (i think) strength its like he is the most precious member of the pack. 

-- then i forgot what happened. i wanted to know the title so i can re-read it. XD please help!

It's an f(exo) fic. KaiSoo, KrAy.
