@zz2000 admittedly i haven't actually played this game myself (i'm just a big fan of the character artist), but the mobile game "otome yuusha" might apply. however, since it's a mobile game, it might be more rpg-lite like, say, fire emblem heroes, but the elements
are there. the story seems to be based around the romance bc the MC and (one of the many) guys in her... arsenal? and i know it has a skinship function and romantic voiced quotes, so it's def otome but more along the harem route.
as for non-mobile games, i don't know of any 😅 i'm sure they're out there, but they've never been in my online periphery 🤔
quick edit: i know more of RPG games w/ romance/otome elements, like fire emblem awakening and recent persona games, but not otome games w/ RPG elements. (but i assume that wasn't what you were asking about)
