The story is too simple while the thesis is traditionally complex. So if only read it as a game between cat and rat, that's fine, and still interesting. But if treat it seriously, it could be horrible and annoying, because i guess some of us would have same idea as Yue. The reason why some people don't have any action, might just be we won't have such a death notebook. heiei~
PS L is so lucky, coz Yue is smart enough and always thinks a lot befre making any decision (if i were him, i woun't worry about the complicate relation too much. hehe~).
