Maybe longer than my kids have been alive but as someone 35+ years old? I doubt longer than I have(I've been playing the genre since the more known English term was reverse dating sim to boot). And yes, Chou no Doku(AKA Butterfly's Poison) has a female LI, there's also been multiple(sadly mostly gone because app/server shut down) Japanese mobile otome that had a mix of female and male LIs. You don't like the vernacular used on the English side of the fandom? Then go stay out of the overall English otome-spaces because even the otome reddit is a-okay with stuff like this using the term, same with vndb. Or go hang out with the worst of the worst like the self-righteous tween LADS girlies on TikTok. o7
