i can only speak from my experience playing but i think enstars tries to push the otome aspect a lot, while also catering to the fujos
only somewhat. the boys all have unique interactions with the producer, you'll get a lot of them that want to protect her or joke about dating her etc. there was an event i played called date plan a-z which felt otome-y as fuck.
but despite that the western fanbase definitely feels very fujo, they usually only ship the boys with eachother – so i agree with you there, that is pretty much the point i was making.
i think you're right that the ambiguity of yuu makes self inserters feel more at ease though: i remember when enstars got its english version there were people complaining that you couldn't choose the producers gender and shes explicitly a female lmao. enstars for whatever reason seems to have a lot of aidens playing it.
anyway apologies to twst anons for shitting up this thread with an unrelated game
