The hit SBS drama released the BTS photos of the trio making sure that the child actors Lee Do Hyun and Hong Eun Taek can still take time to be kids on set. So Ji Sub, who plays the rough-on-the-edges character Joo Joong Won, was careful to not scare the child actors with his cold image while acting by smiling and laughing with them during breaks.
Gong Hyo Jin also put her motherly instinct on display as she not only looked after the kids but chatted with them as well. Meanwhile, Seo In Guk got especially close with the child actors as the friendly uncle who jokes and goofs around with them.
With the cast getting along so well and their chemistry evident on screen, it's no wonder the drama's received a one-episode extension!
