read thus poem and bare with me

Siera is feared by her classmates and is always wearing a hood. One day yui stumbles in on Siera singing a sad song that makes her cry. When Siera turns around yui sees a tear of blood fall down Siera's cheek. What will happen when the vampires find out? Will Siera find love or will she find more hate?

This is my venting so if I were you then I would not read this. This is a very dark book just to warn you.
