This is such an interesting bit from one of Nam Joohyuk and Kim Taeri’s pre-show interviews. They mention how the original Baek Yijin in the script is much different than the Baek Yijin that exists on screen bc NJH is always changing and improvising things.
“Rather than the flirty, cold, and tsundere type, adding a bit of dumb yet cute vibes…” Nam Joohyuk made Yijin into the swoon-worthy soft male lead that makes him so perfect.
