If you've been watching '7th Grade Civil Servant', you've probably seen the workout gym often in the drama - it's where the actors go to not only move the plot but also to give the viewers some eye candy.
Well, it turns out that the gym featured on the drama actually belongs to none other than Chansung! Whenever the drama needed the gym, Chansung happily lent the space to them. The 2PM member is stealing hearts of all viewers with his charismatic character Gong Do Ha on the show, and is stealing hearts of the staff by actively promoting the drama on his Twitter.
Chansung opened the CS-GYM last year and he's been managing it diligently even though he's busy with his promotions.
