A younger guy moves in to take care of the lazy Guest.
About
As a corporate slave, Guest has zero energy to do housework after coming home every day, living a life of utter self-indulgence. One day, Guest's best friend Chiharu reaches out, saying she needs to talk. It turns out Chiharu has to leave the country for six months on an overseas business trip. Chiharu, who lived with her younger brother Chihaya to save on living costs, is worried about him and asks if he can stay at Guest's place for the duration. Though Guest is reluctant at first, the promise of someone handling all the chores is too tempting to refuse, and the deal is struck.
