As Daikichi juggles his work with his responsibilities in taking care of Rin, he takes her to his parents' house. As Daikichi looks through Souichi's house for clues about Rin's mother, he finds an out-of-place modem. When he asks Rin about it, she mentions a maid named Masako Yoshii, who was listed in Rin's health booklet. When Rin wets the bed again that night, Daikichi understands her fear of death and reassures her. The next day, Daikichi requests a transfer at his job to better fit his time around Rin.
