My voice to you

Cheong-ah is a deaf. She is a college student who reads people's voices and communicates with sign language. Cheonga's goal is to direct Antonchehob's seagull in sign language only because she thinks sign language is a language and can express and sufficiently convey emotions in sign language. However, actors Sung-chan and So-jin, who play the lead role of the seagull, are unfamiliar with sign language and keep making mistakes, and the conflict between the three people who do not understand each other is deepening.
