Help with a unknown manga about an old man and a blue demon

Hello, could someone please help me with the search of a yaoi manga. I can only remember the storyline and just cannot figure out the title. I read it on the site myreadingmanga.info
The whole manga is in full colour. It is basically about an middle aged old man with brown hair and a beard who lives alone in a house. But there is a blue demon/monster stalking him, saying he wants him to leave the house. The old man keeps refusing saying it is home and he keeps living there. One day the blue demon sits on his bed and the old man says they are both lonely. And then they do it.
Maybe I am wrong about some points in the story since it has been a long time since I have read it. Does anyone know the title or have the link? Pretty please I am dying to read it again ;-;

<SPOILERS about the story later on>











Years pass as a new family wants to buy the house and there is a rumor about the death of an old man. In the end it you see the old man carving a wooden figure. He has died and is a ghost. The demon has buried his bones many times. He tells the demon to let them have the house. And at the end picture you see the wooden figure of him and the demon.
It was so cute and sad...
