Plot
Some people have the power to enter other people's minds. They can control the others' memories and use their power to eradicate mysteries, cases and even to assassinate. However, the power is so strong that it can backfire and destroy the user's heart. To counter it, chains are used to lock and protect each other's weak and dangerous heart. From one's growing fear and disdain, they are consequently called as a "Pet."
