I am so excited for upcoming drama Ruler: Master of the Mask.  You literally could not have filled it with better sageuk actors.  Both Kim So Hyun and Yoo Seung Ho are sageuk veterans, having acted in some of the biggest historical dramas practically from birth…. OK, maybe 6ish or so …. but it is close to birth.  Thankfully, these teasers do not disappoint and you can tell from the latest that they will have oodles of chemistry.
