Hey if you look closely in the band that Nakanaka is playing, the one who sits on the piano is Yamai Ren ! in the page 16 it looks like she's arguing with Nakanaka but they just go and play anyways.... Anyway, I ship it!
I believe there will be two other chapters of the festival. Tadano and Manbagi and the prom chapter. Will Tadano and Komi dance without interruption? Happy birthday Komi.
