Chen Xiaozhou suffered an accident after falling out of love, and since then he has often seen large groups of “quacking” rubber ducks, which has brought great obstacles to Chen Xiaozhou's life. Until a girl named Feng Jianan appears, Chen Xiaozhou is surprised to find that as long as he is with Feng Jianan, the ducks won't run out to make trouble, and a hilarious romantic journey begins.

At 17 years old, as the only hearing member in her hearing-impaired family, the girl has long navigated between her family's silent world and the outside world of sound, growing accustomed to serving as both bridge and interpreter. Their love and dependence entwine her like creeping vines, yet within her heart rages a fierce flame of longing for a broader world. An unexpected upheaval forces Yu Yan to confront the dilemma between pursuing her dreams and protecting her family. Through the crucible of growing pains, she begins to carve her own path while seeking a melody she can share with those she loves.
