Dear mute man, believe me, I really know sign language.

Qin Yihe, the heir to a mafia family, unexpectedly becomes mute and loses his voice. His tyrannical stepmother, with ulterior motives, orders a nationwide search for a daughter-in-law. Ruan Ruan, desperate for money, assumes it's just a sign language interpreter position. She casually learns a few sign language videos and applies, unexpectedly being selected. Only after being chosen does Ruan Ruan realize that she wasn't selected as an ordinary sign language interpreter, but rather as the fiancée of the mafia family heir, who also serves as a sign language interpreter. However, Qin Yihe is cold, misogynistic, terrifying, and ruthless, killing without hesitation. Ruan Ruan is terrified and wants to get off the ship.
