i found out about this show just when i finished watching Hwayugi/ A Korean Odyssey which Lee Seung Gi was the lead role. i just cant get enough of him and so i started searching what other shows could he be in since his discharge from the military. and im glad i found this! i loooove everything about the show. from the CAST down to the story.... overall, the scenes were fantastic i just cant stop laughing it really staves off boredom. also this show is not only just about fun but you will gain a lot of insights about life as you join the journey of the casts every time they live with their masters. it entertains me lot and got me hooked!
ALSO, since Goblin's ost-Beautiful was played in some scenes (obvviously because Sung Jae-a cast from Goblin was part of the show) i hope they would also play When I Saw You-the ost of Hwayugi. really soothing to the ears!
