Vampire Knight

Nobody Knows

Psychological suspense thrillers with similar themes and great art and both have a sense of mystery to the story. Vampire Knight is a Japanese shoujo though while Nobody Knows is a manhwa, the settings and such are pretty different and Nobody Knows is more psychological and more scary. They have art that is really good at setting the mood. Both stories are pretty complex and you have to read them carefully and then read parts again because of flashbacks etc, so they are more complex story wise than the average shoujo.
