Together with Oniichan - S1.E9

This episode is the start of Season 2. Ayako-san is invited to meet Mamoru-kun's family. Itsumi-chan has a problem cooking for some weird reason today so Mamoru-kun and his mom go out shopping. Ayako-san helps Mamoru-kun's younger sister, Itsumi-chan, out with cooking and learns a little more about the relationship between the two siblings. When Itsumi knocks over the curry Ayako-san runs and gets a rag, the one that Mamoru-kun sleeps with, then Itsumi-chan tells her that is the blanket Mamoru-kun sleeps with and it is partially colored yellow so Itsumi-chan puts it in the curry to make it all yellow.
