I love the way Kanon slapped her and went "Hentai" as if she's used to doing this every single day. I also love how casually Riho walks up and just does it without any remorse or embarrassment
XD
Also I love that episode of Maido Arii. Those segments were always my favourite. Yuuko/Sayu action and Eri embarrassing that weird character were both the highlights of Hello Morning in general for me.
