Ririka was screwed by the retarded management who convinced her that male collabs were good for her/regloss.
I'd bet the same happens with EN. Like, ERB was hired because she was ok with male collabs, Bae is often at the front of stuff because she's basically the only one (with erb) who is ok with mentioning males on streams, Shiori had the bulk of male collabs right around the time the boys had their 3d + henma is a male collaborer.
Like, obviously I am not absolving the girls here, I am saying the managers should tell them to stop being retarded instead of enabling them.
