My SK friend encouraged me to watch K-Dramas and fast forward, so hooked on them. Coming 'late to the table', watching K-Dramas, this was a good Drama. I loved the chemistry between actor/actress and the supporting cast was good too. Loved every suit in 'Mr. Jang's wardrobe. Anyway if you are like me, watching this Drama which aired in 2017, its so fun and enjoyable you won't be disapointed. I hope to watch them all. Work and sleep will definitely suffer. Of course, like all K-Dramas you have to re-watch more than once.
