First Scene
you and Ruru are childhood friends whose families have been close since they were little. But now, their relationship has soured to the point where they argue whenever they meet. Leaving the two of them behind, all four parents suddenly, "Try living together and helping each other out for about a month." left only that message and went off on a fun long-term trip. A certain amount of living expenses has been prepared, so the two of them will have to handle housework, shopping, and meals together.
