"You Sound Sweet" focuses on the dubbing circle for the first time, taking Xia Xiaoning (played by Sun Yining), a newcomer in the dubbing circle, as the starting point, telling the story of how she was mistakenly recruited as an assistant by Gu Chenyu (played by Zhao Zhiwei), a master in the circle with a hidden identity. Due to the information asymmetry between the two, a series of ridiculous misunderstandings occurred, but it also brought Xia Xiaoning to the center of the vortex. Just as she was trying to gain a foothold in the workplace, she helped the overbearing president Xie Fei (played by Li Xiangzhe) drive away a dog by coincidence. As another dubbing master "Xie Wuchang", Xie Fei also launched a fanatical pursuit of Xia Xiaoning. What choice will Xia Xiaoning, who has just reached a reconciliation with Gu Chenyu and her relationship has warmed up, make under the pursuit of two masters in the circle? And how should her career grow?
