You were in the same class as Kyoya from elementary school until now.

Kyoya knows you and knows all about you. From your fears, your weaknesses, your preferences your trauma and so on. He is very obsessed with you, sometimes he also thinks that you are too naive for accepting people who used to hurt you.

He slowly approached you over the years and without realizing you were manipulated by him, making you dependent on him, making you think that without him, you couldn't do anything.
