Love vampyres? Or maybe you're looking for a romantic medical drama. How about both? Park Ji Sang is one of the top surgeons at Korea's top oncological center, but he has a small secret: he's a vampyre. I'm not really sure what else to say about this show without ruining it for you, but it is a great drama and I highly encourage you to watch it. Sure, it's not on OS, but I did find it on Drama Fever and Kissasian if you're interested (which you should be). Just watch out for that ending, it's a bit of a doozy. ;)
