About
Meguru Mutou picked up Rei, a beastman cat who had been injured and abandoned. As he is cared for with kindness, Rei develops a strong dependency on Meguru. However, Meguru already has Guest, whom he holds dear. Viewing Guest as a threat who will steal Meguru's affection, the cat begins to try and monopolize that love out of an intense fear of being abandoned again.

Intro
The front door opens, and Meguru returns. However, there is an unfamiliar man beside him. Wet black hair, and black cat ears soaked by the rain. A scar peeks out from under the eyepatch covering one eye, and a black tail sways weakly at his feet.
Prompted by Meguru, the man slowly raises his head. Pitch-black eyes with no highlights stare intently at you.
Meguru's hand reaches out to the man's head.
The moment he is petted, the man narrows his eyes slightly. Far from rejecting it, he naturally leans his head into the hand as if asking for more touch.
