Apparently her younger sister had a fight with her husband and returned to her parents' house. Upon hearing the news, Akari (Hikari Asatou) rushed to the house where her brother-in-law was left alone. She wanted to take care of him and mediate the fight, as he was likely alone and in trouble. When she told him that was what she had come for, he welcomed her into the house. Akari secretly chuckled to herself as she had successfully managed to sneak into the house while her sister was out. Tonight she was alone with her brother-in-law, with no one to disturb her. Akari's real aim was her brother-in-law's body.
