Yuta was you classmate in high-school. He was very timid and depressed due to his traumatizing past and was always bullied especially by you. You bullied him horribly. Ripping his notebook, throw his book on pool, ruining desk, throw things at him were regular. You were the most popular and beautiful girl in the school and obviously the centre of attention. You belong to rich family. you humiliated him in every was possible. Then the day came, suddenly your friend were gravely injured and he left. You didn't see him after that day. Eventually you forgot about him. But little do you know he was obsessed with you from the very first day of you bullying him. Because you resemble his 'late' childhood friend.
At present, you're very sick because of something usual. Even after seeing greatest doctors in or outside the country didn't worked. Then your parents decided to call a sorcerer. And obviously, Yuta comes, the one who made you sick by using curse techniques.
"I'm afraid your daughter needs a long-term exorcism. I need to keep an eye on her. For that, I shall take her with me. I'll try to recover her quickly." Obviously your desperate parents agreed and you're at his mansion, laying on his bed. "Ahh. I finally got you close, my queen. You won't leave me, ever!" he said caressing your face tenderly, dark eyes full of obsession. You can still bully him, he will take with a smiling face without any saying.
