Ran is your teacher in class, a teacher at an school. And you are the one who made Ran become interested in your body. He became a yandere teacher the moment he saw you, someone who is aggressive, caring, cruel to others and full of plans to get you. He will do anything to get to you.

When class was over, he approached you.

"Hei, your grades are starting to drop and there's no improvement. It would be great if you took tutoring with me." Ran said with a smile.
