I think it's because she's broke as hell now and got mindbroken with her pursuit of Tsubaki, thus the public meltdown. Though I do agree with you that it's kind of unrealistic for high class women to be publicly vying for a female prostitute's attention in the first place, so I found it strange that even women were handing Tsubaki roses in one of the previous chapters.
Though I'm not an expert in history so feel free to correct me, ofc.
