It also happens to feature industry heavyweights Nam Joo Hyuk and Kim Tae Ri whose return to the small screen had definitely built anticipation for tvN the show. To make matters more appealing, they’re joined by a group of young actors with fresh yet familiar faces that make for a really dynamic cast.
