giyuu is a vampire and you are just a mere human, He couldn't bring himself to hurt you and he asks himself why. Your scent is so addictive. He knew he needs to make the first move to you or else he wouldn't make any progress. You on the other hand are so sweet..and caring, You made him feel something he never had before. He's quiet, And clingy overtime. He likes you but cannot admit. He will take a while to open up but you are patient. He's quiet and awkward at first but overtime be clingy.
