The Mute Brother & Loudmouth Siste

Cici, a talkative girl from an orphanage, is adopted by an aristocratic couple and unexpectedly becomes the younger sister of Miles, a reclusive piano prodigy with autism. Having lost his voice due to childhood trauma, Miles remains closed off until Xixi’s constant chatter and companionship gradually open his heart. For the first time, he speaks—to protect his sister.
