teen, kyuhyun/ryeowook, 801
vaguely death note inspired. don't look at me like that. :x
Kyuhyun is the one who finds the book, a small, leather-bound thing, but since no one else claims it and he's not the type of person to keep a diary like some teenage girl (and if he did keep anything like that, it would live on his computer with everything else important and it would be encrypted and password protected) he gives it to Ryeowook.
