I just stumbled upon r-18 stuff of otome cd's.... I just know english....... is there a way to understand the scripts, the context n stuff like how people understand the raws of asmr in japanese ....... sorry if this answer is considered cringe....! T_T
There are some drama cds with english translation included. You can also google for a fan translation. If you're a weeb then most drama cds are pretty easy to understand since the content all involving *cough*passionatehugging*cough* tho...
As for otome games, there are some caption translate programs you can use to roughly understand the plot.
Sorry to bring in the news, but this one just got updated again not too long ago. I'm not terribly interested in the game, so feel free to take your time to update it. 敗戦隷姫エルネア to v25.04.23
