On the 2nd, KBS 2TV's 'Documentary 3 Days' aired a special video about the BTS of 'Generation of Youth'. The documentary showed the staff working day and night without even a moment of rest.
During the interview, Kim Hyun Joong said, "If a drama becomes a hit, the actors get everything in profit. To be honest, the staff doesn't have any other reward. All they get is the satisfaction that they participated in the drama."
He added, "Even though the environment isn't improving at all, all the staff work even harder to make a better drama on another level."
