To be honest I think what you have right now is a good balance on the scale between vanilla and fetish. I don't think what you have made so far is completely vanilla, it has plenty of flavor to it.
Personally I dislike it when VN's cater to fetishes too much, especially when they are not straight up Nukige's. So I agree with the stance you are taking with the new route you are working on. Basically a good middle ground that does not alienate many people.
Had another go at the game after a long period and enjoyed it. It's not easy to pull off Yandere in an attractive and/or romantic way and it's rare to see it done well. Too often, in VN's that feature this type do they make them into one dimensional antagonists without enough redeeming features or relatable motivations, making them too difficult to like resulting in them being off-putting.
Not the case here though. Nice to see a writer that gets it and understands the appeal of that type and focuses on said appeal to support her character, so props for that. I have a new fave character now.
Looking forward to checking back in the future to play her finished route (where I assume the player chose nobody else and only her, which would be nice) good luck.
