I need some help

Hello guys ! I hope you can help me about a manga.
(I think it's a amateur story) - the story talk about a man who lives into a small house where a ghost wants his leave. The ghost is like a demon. The story is very short (a one shot). Little by little, we can understand that the men isn't alive but dead and the demon protects his bones under the house. The demon and the men are in love with eath other.
I really hope you can help me 'cause this manga obsesses me (〜￣△￣)〜
