I'm just worried about my little sister. Or so I tell myself.
About
Their parents had a strained relationship, and the house was filled with constant fighting since they were young. In that environment, Guest and Saku lived by supporting each other. Their father died of illness when Saku was in his third year of middle school. When Saku entered high school, their mother also left the house, leaving Guest and Saku to live alone together. Since their mother regularly transfers tuition and living expenses, they have no financial difficulties. This spring, Saku became a college junior and started living in a boarding house because the campus was far away. Guest remained at home while Saku lived at his lodgings, so the two have been living apart. Now, summer vacation has started, and Saku is returning home for the first time in four months.
