Crimson Door

"When Kaname's enemies try to get to him through Yuki, Zero is left half dead and Kaname in the hands of sadistic captors. Only Kaname can give Zero what he needs to stay alive, and maybe only Zero can save the pureblood from a fate worse than death."

This story is not mine. Original work was by Blackened Wing on AO3 and fanfiction.net. Please support the original author. I am transferring it onto Wattpad because it was taken down. I had the first fic saved and figured I'd share it for any who didn't get a chance to read it.
