Jang Dongwoo. A 16 year old student at Dongwan Highschool. Due to a disease he carries, he is not allowed to see

the sunlight until the medication stops and because of that, he is being transfered to the late night classes that

the school has. Those classes are not ordinary classes and the children that go there are not ordinary as well. 

His classmates are not human, some of them are were-wolves, some are vampires. 

The school, though, didn't take into consideration the fact that his classmates were out of the ordinary and they

forgot to tell him anything at all. He was, in fact, in great danger, until he met this other boy who happened

to be the leader in the classroom...
