Sōta tries to study while Kanaka and Ayuko continue playing Jenga. Kanaka invites Sōta to take a turn in the game, and while he tries to move a brick, the tower crumbles. Being the loser, Sōta is pressured by Kanaka and Ayuko to buy snacks and drinks. He even discovers that Saki isn't really asleep since she tells him what drink she would like. Later, Sōta returns with the snacks and drinks and he and Saki play a PSP game, with the latter remarking that if she scores badly in her tests it'll be Sōta's fault. The next day, the girls once again show up in Sōta's room. Irritated he goes to clean Kanaka's room so she can entertain guests there, to Kanaka's appreciation but Saki remarks that Kanaka is a terrible sister.

こんにちは、天谷奏香の弟の颯太です！
いつも姉がご迷惑をおかけしてます。
前回から引き続き、みんながうちに来ているわけですが、姉が部屋を片付けるわけもなく、相変わらず好き放題。
理不尽な仕打ちを沢山受けました。
中学生にして接待というものを覚えた一日でした。
はあ。。
