Recommendations [BL] Unlimited Flow novel with ghosts friends

Unlimited Flow novel where MC "collects" and befriend ghosts. The ghosts help him and protect him. Something similar to "I Wasn't Born Lucky" and "Opening a Shop in the Nightmare World".

The NPC Was Once Again Frightened By Me
He's kinda a ghost himself, but human too. He's helped ghosts and some ghost helped him. I mtld most of this was mostly understandable.
