Im really glad that Ichi had a chance to get out otherwise everyone in the room would be swimming in semen. Also damn it gals let the man visit his darling.
I might be wrong, but this might be one of the few (if not the first) times that we have had a chapter title that could be used from Yamadas perspective
There's an interesting change in the anime adaptation of the moment in the top right corner of page 8. The girl who "pops up" on page 7 is Andou Kanna and not Yamada Anna, which can be seen in the manga by: 1) color of the hair, 2) different background to what's behind Anna, and 3) the name tag shows 安堂 (the first kanji is pretty clear, and the three strokes at the top of the second one are also visible.
I watched the anime first and assumed that the manga showed Yamada with the darkened face after she touched Ichikawa's erection (which itself isn't in the anime – Yamada reacts only to Ichikawa's line "I want to talk to you about something"), but I've only noticed the difference on my second reading of the manga.
