On the topic of Chino’s height, Rize says it would be funny if Chino outgrew Cocoa, as this would put Cocoa on the receiving end of affection. Cocoa is fine with this, but Chino assures her she won’t.

「あ (わたし)()きついたりとかしないので大丈夫(だいじょうぶ)です」
“It will be all right because I won’t do things like hugging you.”
