Just because he was a heart of darkness didn't mean he wanted to be stuck in the Realm of Darkness. Just because she was the only other one there didn't make them friends.

(Edited reupload of Cast a Shadow, Another Side Another Shadow, and Shadows Alight, no longer discontinued.)

Just because he was a heart of pure darkness didn't mean he wanted to be stuck in the Realm of Darkness forever. Just because she was the only other one there didn't make them friends. And just because they were going to spending a whole, whole lot of quality time together didn't mean she could change him. Rated T for violence and emotional disturbances. For Aqua/Vanitas Day 2014.
