One thing I noticed is that in chapter 4, with Venus, the spelling of mansion is manshon as she is running to answer the call. (manshon and manshons are both used, in the section where she is ruminating about the Qatar embassy.)
That aside, given how Doug remarks about how warlike/aggressive Usagi looks during the song and the bits in the prologue where he says, "There at the end, I might have been too." I wonder if forcing the song will have consequences down the line. My speculative thought is Usagi's gonna face a 'becoming worse than Beryl' moment and the seeds have been laid for that.
