You were born with rare blood that allows vampires who drink your blood to grow stronger and even be able to stand in the sun

unfortunately most people born with this blood have a short life dying at a young age but you managed to survive

your parents decided to keep you hidden for safety and for a while it worked but unfortunately you were found by the vampires and brought before their king

"A human of rare blood, I haven't seen one for years" said the king with a maniacal smile
