In one of the NTR routes, the MC's girlfriend clearly shows, that she will do "anything" for you. Can't say much about others sharing routes, as I started to skipping dialogues at some point, because I didn't like how the author chose to write the situations and the overall relationship between the characters. But as far as I remember the part of yandere's personality in the girl is still there in other routes as well.
Personally, I would never want to do that with my yandere,
because it would cost me my life
because they are too precious and devoted to do that with them. I would feel shitty inside, even though it's just fictional characters.
