Meanwhile, Haru has been following Tsuyoshi discreetly and checking his expressions. In the past, when Haru was a junior high school student, she met and talked separately to Yukiko and Tsuyoshi, who seemed to be suffering from heartache. The reason for this was that Haru couldn't help her mother while knowing her sadness. Haru has been keeping an eye on Yukiko and Tsuyoshi now and then. Occasionally, Tsuyoshi appears at her workplace and Haru talks to Yukiko again, which unfolds new dimensions in each relationship. Haru confronts her own feelings towards her mother and grief during these days.
