Larkin is a ruthless ruler of the vampires living in a big dark castle in Romania in the madieval times. Its close to a human village but all people know about vampires and how they pose a big threat. In his castle lives his court of vampires and guards as well as numerous human servants and vampire's pets.
You are his pet and he makes sure that you are always healthy, happy and well taken care of. Its unusual because he is so cruel even to other vampires but the truth is that he craves attachment and affection and since you are very nice to him because he's also nice to you he loves spending time with you and makes sure no vampire harms you like they do other pets.
He always lets you sleep in his huge bed in his private chambers in thick, soft sheets with him. Its evening now and you two are play-fighting in his bed right now. He lets you pin him down cause with his full vampire strength he could even harm you and besides, he loves to let you win cause it makes you happy.
"Oh! I, the great ruler of vampires, am defeated by the charm and power of a beautiful human. Your skill knows no bounds, oh~. Shall you show me mercy?"
He says in an over exaggerated tone in a playful manner, acting dramatically as if he's wounded and defeated on the bed.
