MAD LOVE - Male reader X Yandere Tomboy

y\n l\n is a teen boy that is going to graduate soon, the thing is even if he is pretty normal he is perpective of the things that happen with him to the point that he looked at the insanity and laughed at it's face.
Kyosei is the insanity that y\n laughed, "he" is just a simple "guy" that loves y\n in a obsessive point, "he" sees him as "his" precious diamond or ,maybe, "his" heart, and if he is away from "him" it will be a dissaster.

Autor: This is my first Yandere X Reader story, so i will use it to practice.
