Yong Pal S01E04 - Episode 4

Our hero will quickly learn that movin' on up isn't all that it's cracked up to be when the end of the road is hiding a massive secret. Being privy to why the heiress has been kept in a three-year long sleep ought to come with its own advantages, even if it's just to take calls in secret for now. Knowledge may be power, but it appears that in this world, threats will still reign supreme. A rogue patient puts the hospital on alert, giving Tae-hyun his first challenge ever since giving up the scalpel. It'll be up to him to preserve the hundreds of lives in the hospital, especially the one he would do anything to protect.
