Misplaced Soulmates! {BxB}

'Story Status: Incomplete'

In 1 (one) of the 4 (four) realms that angels inhabit is where our 1st (first) protagonist/main character spent most of his life in. His name is Lucas. Lucas is known as the "Golden child" since he is the lucky angel who happens to have more power than the other angels in the realm. But in a different realm, there lives our 2nd (second) protagonist/main character, Mark. Although Mark is originally from the Demon Realm he spent most of his life in the Supernatural Realm. Mark is loved by the supernaturl creatures who lurk within the realm due to the fact that he has extra abilities that other demons don't possess. You see, our protagonists/main characters may be different in many ways and live life differently but soon they'll end up having to face the same "problem" once Lucas recieves his soulmate string. Once Mark and Lucas venture out and find each other, together they'll have to search for the answer to their question... "Why are we soulmates?!"
