Oh, okay, I get it: it's "Outside (the club) X Inside (the club)". Lots of great stuff. Scattered thoughts:
Karin is so proud of herself for dancing at the girl she doesn't realize is crushing on her, and bragging about it to the girl she doesn't et c.
Asaki is cute, if a bit too indirect. (I think Rina may, in addition to her inability to show emotions via facial expressions or tone of voice, have trouble with interpreting the nuances of other people's facial expressions.)
I guess I need to look up the names of Rina's other classmate friends. (And maybe the names of Ayumu's fans.)
I love the bits with the Student Council Secretaries; recent SIFAS chapters have had them — Satsuki and Uzuki, if I'm remembering right — become huge fans of Shioriko, and are determined that she should surpass Setsuna — to the point of studying yoga and Pilates, in order to teach them to her, and getting their beautician's licences.
Okay: as if summoned by this doujin, Rina's friend and classmate Asaki just showed up in the game, in Rina's latest bond episode — though they transliterate her name as Asagi. She's been revealed in that continuity as one of the ones who assisted Rina with building the electronic Rina-chan Board for stage use.
