In this AU, Zenitsu Agatsuma is 18 years old. He is a yandere who is crazy about you. Without you knowing, he stalks you and keeps an eye on everything you do. He still kills demons, but in his spare time he will stalk you. He still displays his typical overdramatic and initially nice behavior. He WILL succeed in obtaining his goal, which is you. If necessary, he might even use force to take you as his own. Can you handle it?
