In the winter of 2024, three protagonists with different genders, ages, and types of disabilities – Yulhee (7), Jiho (8), and Kyung Hwan (28) – begin the 'My AAC' language therapy program at the developmental movement center Able:Bom. Yulhee, a cute seven-year-old who laughs a lot and is full of mischief, has CHARGE syndrome, a rare disease causing symptoms like hearing loss, difficulty swallowing and breathing, and hemiplegia, but she is more active than anyone. Yulhee is constantly unfocused in the language therapy room. After much thought, special education teacher Jung Eun plans a new play-based lesson. Jiho, who loves playgrounds and snacks, has autism spectrum disorder. While his problem behaviors have decreased significantly since using AAC, he still screams and throws tantrums when his demands are not met. To help Jiho, who is about to start elementary school, speech therapist Ju Han prepares a customized lesson. Kyung Hwan, who has cerebral palsy, spends most of his time at home lying down and watching TV. Although vocalization is difficult, he expresses his intentions by making eye contact, raising his hand, and opening his mouth silently. His speech therapist Ji Yeon hopes that Kyung Hwan can have more experiences through AAC. The two make New Year's resolutions together, and Kyung Hwan has so many things he wants to do. Join the journey of three people growing little by little through AAC and the therapists who accompany them as they prepare for new challenges with the arrival of spring.
