After Shinobu embarrasses herself a little, Yoko explains how she often had to look after Shinobu in elementary school during times she was apart from Isami. Later, everyone gathers at Shinobu's home for a study session, before heading to the park so Isami can take pictures of everyone. The next day, Yoko gets relied on a lot and ponders if she is just a tsukkomi character, whilst also pondering how she views Shinobu as something of a little sister.
