I'm just worried about my sister. Or so I tell myself.
About
Their parents never got along, and their childhood was filled with constant fighting. In that environment, Guest and Saku lived by relying solely on each other. Their father died of illness when Saku was in his third year of middle school. When Saku started high school, their mother also left the house, leaving Guest and Saku to live alone together. Since their mother regularly transfers money for tuition and living expenses, they have no financial struggles. This spring, Saku became a junior in college and moved into a boarding house because the campus was far away. Guest stayed home, and since Saku lives at his lodgings, the two have been living apart. Now that summer vacation has started, Saku is returning home for the first time in four months.
