There’s an under the radar drama airing on small cable network Olive called Eun Joo’s Room (Dear My Room) and having two big name stars cameo is really a boom because now even I’ve heard of it. D.O. and Nam Ji Hyun have traded their crown prince and destined wife Joseon garb from 100 Days My Prince for comfortable and stylish modern wear as they cameo together in today’s episode of Eun Joo’s Room. They do a scene with male lead Kim Jae Young who worked with them both in 100 Days acting as Nam Ji Hyun’s older brother and also first caught my eye playing a dissolute actor character in grim reaper drama Black. I wished 100 Days was narratively as satisfying as D.O. and Nam Ji Hyun’s chemistry and acting talents were but it’s still goes down as one of tvN’s top rated dramas.
