Demonic hearts (yaoi) Hydra x Nathan

Seeing them

I'd knew that the insane souls of the lost chambers would come after me. Lost and all alone. They walked down the halls, knowing that this is their death bed. Those who enter, awaken them and the demon kills that person and the souls sleep again.

At first, I thought he was soulless but he starts protecting these souls and puts them back to sleep. I walk toward a large door. I opened it with hesitation. There was a plack on the wall. "As cold ice will be the cold air for those who are aware." It said.
I walked past a fire place with a furious fire dancing upon the logs. Soft chairs sit and the room looks cozy.
The floor cracked underneath my feet. I fell. Hanging onto the ceiling.
