Disappearing of young men was all over the city, sending horror to the citizens, at the same time, alarming the police. When some of the missing men were found, they are already dead (most likely brutally killed) with different parts of their body removed and the authorities are unable to find the missing body parts along with the suspect. Most of the disappearing was happening inside the Paran Academy. But Cho Kyuhyun was not scared about it and still enrolled to the said school.

There, he met the silent loner, Kim Ryeowook.

Ryeowook had walls surrounding him and Kyuhyun had a hard time entering his life. He was so mysterious for him, but then he was able to walk through those walls, able to see the real him; Ryeowook was cutest, adorable (yet shy type of guy) and unbearably beautiful man Kyuhyun had ever met. When time passes by, he became romantically attached to the boy and promised to protect the vulnerable Ryeowook from being one of the victims of the mystery, psychotic killer.

Cho Kyuhyun:

Kyuhyun is a good, productive man with a kind heart. Though he could be playful and will suddenly turn into a prankster, he is a man who changes people's hearts. His main goal in life is to make lonely, and alone people become the opposite of it and change their lives.

Kim Ryeowook:

Ryeowook is the dead kid in the school. He was the kind of student that you will never notice if he's present in class or not (though he's an ace student too). He could be really quiet and some might say that he's heartless but he is actually a loving brother for his deceased hyung, Kim Jongwoon.
