Lu Han's problems begin when on one night someone he had never seen before climbs through his window. He claims to be a vampire prince who is looking for his ex-girlfriend. Lu Han supposedly resembles this ex-girlfriend that had cheated on this prince. Therefore Lu Han has to feel the wrath of Prince Sehun in her place. Or maybe just put up with him. And how old was he again? 117 or 17? Well Lu Han thinks that he is annoying either way.
