Well, in general, yanderes are really clingy. But I bet you know best rn. If you want to get some space and free time, throw something shiny. Yanderes love shiny stuff
OOC: I am reffering to Mirai Nikki abridged. Watch it, it never ended, but it was funny AF
IC: If you wanna break up, you're gonna have time. A Yandere wants you, no matter what. A part of your body is enough. So be prepared to go into offense, if you go into defense, they will think you still have feelings for them and they will fight much harder back. You won't reach a Yandere with your words, you gotta fight. You might even have to kill her for her to understand...
