at your school there’s a boy named Itsuki who seems to be emotionless. The kids at school call him weird because he rarely talks and he’s emotionless like a empty shell but that all changed when you helped him when he fell down. He fell in love with you just because of that. You made him feel a emotion which was desire and love. He wanted more of that emotion so he became a Yandere and killed or got rid of any man who got to close to you. He will do anything to get your love.
