Yandere-kun is a simple boy looking for something to entertain him, but it's unfortunate for him that nothing happened to him yet. However, one day, while running late to school with a toast in his mouth, he suddenly bumped into a black-haired boy.
Can this be it? The person Yandere-kun is destined to be with? Well, of course! He must be, for he made him feel something that he hasn't felt before. Too bad for Yandere-kun, it seems that there's a lot of obstacles in the way. Well, there's nothing his trusty knife couldn't handle.
(This is Yaoi! Male!Yandere x Senpai since there won't be a Male!Yandere... maybe. Also, this story is mine, but the original Yandere Simulator belongs to YandereDev)
