Alternate Universe (From Supernatural's universe)

The lives between two guys whose clique falls apart after the disappearance of their loved ones.

Castiel Novak, who is half-blood from DEMON and ANGEL, purposely lost his brother, Gabriel Novak, for the crime he committed in the heaven and dimensional world. Dean Winchester was a, once, married guy, had a daughter and separated from his brother, Sam Winchester, before the fire accident, when also his mom died.
Who else would have known that these two guys used to meet each other before the beginning of the first chapter, although, something or... someone did to both of their memories, forgotten each other.

Now they meet again.

These two guys are swirling around their lives, struggling on finding their family, their memories and in the meantime, saving humanity. While they will be dealing with supernatural thingy, family and dramas will not ever leave their minds and of course... how closely they are to each other.
Will they ever find their memories back? Will they discover their past?

Note: This is just my imagination from Supernatural's universe. I just want to share my dreams and create another new story, worlds, and alternate universes. Though a few characters will still be available in this story but only for our main characters. I really need to apologize, but in this concept, we're going to discover A NEW ALTERNATE UNIVERSE.
