The trio, known as Eun-Jang-Do for their character names Eun Ho Won (Go Ah Sung), Jang Kang Ho (Hoya), and Do Ki Taek (Lee Dong Hwi), are always together as three people who suffered from the difficulties of looking for a job before finally landing a temporary job together in the same team.
In one still cut, the three are fuming after getting their souls sucked dry by their senior, Ha Suk Jin, and plot some sort of revenge. In another, the three can be spotted bawling on a bridge, while cops and reporters show up. The third still cut captures their first meeting, which takes place in a hospital.
'Glowing Office' tells the story of Eun Ho Won, a woman who decides to live wildly after finding out that she has a terminal illness. It premieres March 15 at 10 PM KST. While you wait, you can watch another teaser for it below!
