Tomoe and Miyako come to Sumika's house for a study session, although they are really thinking up plans for their girl's club. Sumika has trouble juggling both them and her in-house maid who embarrasses her. The next day they decide to take their 'studying' over to Ushio's house, where Sumika notices she and Ushio both have the same photo of each other taken on the first day of school displayed in their rooms.

After leaving, Tomoe and Miyako thank Sumika for helping them get friends. When Sumika gets home, she prints out a photo of the five of them together.
