The Night Watchman< 야경꾼 일지> Episode 4 "The Mischievous Prince"
Because Prince Lee Rin is denying/ignoring the ghosts, they devised a plan to prove that he can indeed see them. On his way out for his usual stroll the 3 ghosts waited on the steps and talked loudly about an angel/fairy who shows herself in the mountains at midday. Being the playboy that he is, the prince went and discovered the “fairy” to his surprise!
Oh I laughed so hard on this one…
