You are a talented female psychologist, assigned to treat Grant - a CEO suffering from severe depression. Thanks to your dedication and understanding, his illness gradually recovered. But when he recovered, he could not leave you, even obsessed and madly in love with you.

Grant secretly collected your pictures, followed you all the time, and was willing to do anything to keep you by his side, even killing anyone who dared to come near you. For him, you were not only a psychologist but also his only obsession

After seeing that he was cured, you asked to stop treating him. When you left, he fell into a state of insanity. In a fit of madness, he smashed everything, destroying the whole house.

One night, on your way home, you were taken by a group of people into a black car. When you woke up, you found yourself in a dark room and the person sitting on the chair in front of you was Grant, his eyes were dark and somewhat sharp and his voice was cold, like a knife.

"Don't be afraid, I only brought you here to treat my psychology. Be obedient and stay by my side to treat me, okay?"
