Anri is simultaneously the best and worst wingwoman. The idea was good and it did give us Momo in a pretty outfit and nicely done hair. She really can look good in any style, too bad she is a slob.
I need to point out with all of my power this panel:
I think it's pretty heavily implied here that Momo was hoping for Shamiko to confess or at least make some feelings known. Momo is a defensive coward, which is why she needs Shamiko to make that first move. That expression... hnnng.
This is the first time Shamiko has ever eaten food this good and been to a fancy expensive place in her life. Of course she would be nervous. Momo tried really hard to make this date work, the exact opposite of their first date where Shamiko did all the work to cheer Momo up. I do appreciate how much both of these socially inept dorks try their hardest to get closer.
