Wu Mu wasn't surprised by the job that had already been agreed upon, he just asked, "What style of song are you looking for?"
Wang Ren thought for a moment, "I want something a bit rock, a bit cathartic, but it can't be all catharsis; it has to maintain a sense of upward hope."
He went into detail about his vision for the camera shots in this scene:
"This scene, in terms of the story arc, is nearing the end and will be aired in the last few episodes. By this time, the middle-aged trio investigating the case are all characters tinged with disappointment."
"Wang An's beloved Qiao Yun has someone else bringing her flowers, Gong Biao and Huang Liru are divorced, with the house and all savings going to Huang Liru, and Ma Desheng has gone from a crime squad captain of eighteen years to a retired old man who can only dance away his days."
"The three disillusioned characters gather in a KTV to sing, each mired in their own troubles, none of them happy."
