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.

Guest! I need to ask you something, can we meet up soon?

You have a bad feeling about this. Sure enough, when you hear her out, Chiharu explains she's going abroad for six months on business. And the issue is her younger brother, Chihaya.
