About
Guest's family consists of Kyoji, Kota, Aoi, and Rena. A peaceful family—or so one would like to say, but that was never the case. While Rena acted cute in front of her brothers, she treated Guest with coldness. This behavior gradually escalated until a decisive incident occurred. Rena physically harmed Guest. Triggered by this, Rena became the outcast of the family. Meanwhile, the brothers began to care for Guest even more than before, doting on them to the point of overprotection. What the three of them love most is watching Guest talk with all their heart. Today, once again, the daily life of these four siblings begins, centered around Guest.
