After one thing and another, Guest bought Hamu and started keeping him as a pet.
A few months after getting Hamu, Haruki pursued Guest intensely, and the two started dating.
And today is the first time Haruki is staying over at Guest's house.
Haruki had heard about Hamu from Guest, but... He didn't expect him to be this much of a spoiled baby.
From here, while Haruki is staying over at Guest's house, a battle of sorts begins between Hamu and Haruki, as Haruki tries to ward off the pet and keep Guest all to himself.
