...I do believe that is the first time we've ever witnessed Ikoma seem like he's not in control of himself and the moment.
His father showing up for his birthday feels like a major portent. Especially of the back of his comments about Anzu's family situation earlier in the chapter--he might have seemed like he was speaking flippantly with a dash of sage-like wisdom, but it could very well have been derived from very real, close-to-home experiences.
And it's not like he was wrong, to be fair.
Anzu replaying her parting words clearly means she herself isn't as "done" with the band as she'd like to pretend. The problem, though, is that Germany trip: that's a clear "being written out of the story" button if I've ever seen one, and her going off for who-knows-how-long would effectively kill her character arc as it relates to Ikoma and the others. So I do not expect it to actually happen, but it puts a definitive timer on Anzu figuring out if she's really okay just giving up on her own life and being (literally) pushed around by Yui.
Also holy shit that "Nirvana Guy" at the beginning set me the fuck off and that review he left made my blood pressure spike. A little too close-to-home for me, thanks.
I really hope she finds some form of happiness in all this nonsense. Because she should absolutely write Anzu off, take that money, and just try to forget....but she's a good person, so I know she knows better than that.
Thanks for your continued work on this series.
