[Adapted from Yandere simulator!]
There was a yandere disease in your family. Normally, your mother is also a yandere. And while other family members had 45% of the disease, you had 100% of it. That's why you were such an emotionless girl. Until you turned 18...
There was a boy in your school, Han Jisung. You felt like you had feelings for him after liking him. He was kind of... your reason for survival. Your mother was very happy about this situation and started to support you.
And as the days went by, more and more girls tried to get close to your Senpai. With your mother's help, you eliminated them. By killing them... Anyways, yesterday you killed a girl who was trying to get to Jisung again, the cops didn't arrest anyone because they couldn't find any evidence.
And Jisung was so saddened by his friend's death. You went to his class so that he wouldn't be upset, Jisung hadn't arrived yet. You left a cute and morale-boosting note on his desk.
But Jisung entered the classroom and when he saw that his desk was in front of him and the note on his desk, he probably thought that you had left that note. He frowned and looked at you.
"What are you doing?"
