Lin Mo was born unable to hear. Raised in an orphanage, he learned to observe the world through his eyes and the strokes of his pen. At a charity event, he met Chen Xiao, a flamboyant yet lonely lawyer. A misunderstanding brought them together, and a lawsuit involving the deaf community forced them to work as partners. As a series of events unfolded, they discovered that each other's worlds were far more complicated than they had imagined. Lin Mo was not entirely “silent”: deep inside, he had a keen awareness of the world around him. Beneath Chen Xiao's polished exterior lay the secrets of his family and his past. Amid misunderstandings, cautious probing, and growing closeness, they signed a “silent pact” of their own: they could understand each other's true feelings without saying a word.
