Vampires and Werewolves; immortals who are destined to be enemies.

One rule is to follow: Love your enemy and death will be the only open door that awaits you.

There were some that dared, claiming that their love was strong enough to face anything, yet they all ended up being devoured by darkness, leaving their child to die.

However, a pair of lovers was lucky enough to escape their destiny and successfully kept their child alive, but their lives didn't last for long.  

On the other hand, the couple’s babies were left in the arms of an old lady who lives by herself.

Now, grown up as seventeen year olds without the knowledge of who they really are, both of them clash with destiny as they repeat history for another round with twelve young gentlemen.
