"The Mask on the String" tells the story of the genius violin girl Wen Ruan's journey of revenge and rebirth. When she was fifteen years old, her parents died in an "accidental" car accident. She was adopted by her aunt Wenmei, who coveted the family property. She has since curbed her sharpness and used a "docile" mask to hide her true self, but secretly she has never given up her love for the violin and her pursuit of the truth.
At a charity dinner, she met Shen Yanci, the cold and stern president of Shen Group, who was attracted by the stubbornness in her eyes. After that, Wen Ruan took the opportunity to become Shen Yanci's assistant and handed over the music score containing evidence of his aunt's crime, and the two reached a cooperation in the name of "exploitation". As they get along, Shen Yanci gradually discovers the tenacity and talent beneath her mask, and Wen Ruan also glimpses the gentleness beneath his cold shell. They teamed up to uncover the truth that Wen Mei forged a will and deliberately caused a car accident, and Wen Ruan finally regained everything.
At the exclusive recital, Wen Ruan played "Starlight", which symbolizes hope, and Shen Yanci promised her a future with a ring engraved with string patterns. The mask faded away, the starlight rekindled, and her music and life finally shone brightly again under the guardianship.
