The Story of a Real-Life Yandere

Some people think that Yandere isn't real, but as I got interested to know about them, my dad told me a story about his great friend that was hanging out with a yandere and never escape from her.

* I don't care if nobody believes this story, but everything you will read is what my dad told me. *
*Be careful out there, for they are real, whether there female or male*
