Your miraculous crush goes yandere for you. What happens to you?

I’m bored, so I wanna know. Say your favorite person in the show is yandere for you? How screwed are you, what do they do, and do you reciprocate?

Personally, I don’t even wanna know what Kagami would do to me, just whatever manga advice she’s taking, it ain’t from the write characters.

Anyway, what are yours?
