Furthermore, Sayako (Mizusaki Ayame), who has come looking for Hikaru, barges into the house, creating a tense situation. Kazumi presses Sayako, demanding that she explain why her child is her son. Reitaro tries to stop her, but Kazumi senses that Reitaro knows something, and the two get into a scuffle.
