This is a slightly perverted romantic comedy between a peaceful, hot ghost and a sham exorcist with bad habits!
"How far do you think that you, a ghost, and I can go?"
Iori is a ghost cleaner who was asked to exorcise a haunted apartment.
He was making light of the situation and assuming there was no way there was a ghost there, but when he opened the door, a hot ghost that was 100% his type named Yukihisa showed up!
Iori pretended not to see him, but he ended up staying in that room to exorcise him.
Iori was invited to day drink with the landlord, who is terrified of ghosts. However, Iori has a bad habit of wanting to have sex when he gets drunk, so he ends up doing it with Yukihisa.
Then the next morning, when he wakes up, for some reason he's been possessed by Yukihisa!
