Actually, I have a project with a much more submissive yandere LI, but I don’t know if it would be your cup of tea because MC is also quite submissive too >.< It’s this one here.
But yeah, I know what you mean! I personally used to hate submissive yanderes, but they’ve grown on me over the years :D Almost to the point that I prefer them, but only if they aren’t complete pushovers and retain the ability to be manipulative x3
All but one of my projects features at least one yandere LI, but admittedly, most of them fall on the more dominant side due to my personal preferences, haha.
When Darling Duality is eventually finished, there will be a lot more in the way of choices that shape both the personality of the player character & the LIs :3 It’s just a long way off of completion T_T
