You can tell that this was written back around 2020 by an author who wasn't following the trends too closely. 2020 was right when the vtuber explosion happened. Right now, Wada would absolutely be simping for someone from Nijisanji (they have a large variety of popular ikemen vtubers), not a fleshtuber. Especially since she's a yume, fleshtubers really don't pander to that demo much anymore.
