Rin was Sehun's first love. He loved her just the way she was, although she was a murderer or a greedy wolverine. But.. someday, her girlfriend was dead, killed by a mysterious guy. Since that day, Sehun lost his life. He's live like no soul. So empty. Kai, his little brother is so worried about the cold prince. He's afraid, the young prince will forget about his status as a prince. He has a big responsibilty of vampires's life since they live in the human's world.

Kai is trying hard to take the old Sehun back. Maybe with finding a new person in Sehun's life to fill Sehun's emptiness as a an annoying brat little borther, he thought. 

Luhan is a human. He's an exchange student from China. He's a cute boy with warm hearted. He has a sweet smile and makes another students in the campus, fall for him and even some girls envy towards him because he has a pretty face. He's such a pretty boy. Although he's so famous as a flower boy in his new university, but there's a boy who dont even look at him. it makes Luhan feels annoyed. and he promises will make the cold boy fall for him. The cold boy is Sehun.

Kai knows what is Luhan thinking about, because vampire can read human's mind easily. Kai agrees with Luhan's decision to make Sehun melting over him. He really hope that Luhan will did it and get Sehun's empty heart. So.. yeah.. Kai will help Luhan, of course. and this will be fun.
