Come on. You people greatly overestimate the danger of being the love interest of a yandere. You're safe. In fact, you're a little bit too safe (as long as you avoid eye contact with the opposite gender and keep social interactions with them at the bare minimum required for survival - basically don't do anything that could give her any weird ideas such as confining you to a wheelchair, gouging your eyes out, castrating you, performing a frontal lobotomy etc).
