Kim Hyun Joong's drama comeback has taken three years and is also highly anticipated. The star of "Boys Over Flowers" and "Playful Kiss" returns to the small screen in "Generation of Youth," a drama, which takes place in 1930s Shanghai. He did sign on to appear in another drama "City Conquest" but it never got a time slot and was cancelled.
