In her previous life, Ji Nanxing abandoned her poor painter boyfriend in order to marry into a wealthy family. After her rebirth, she became blind and made a living by tuning the piano in the dark. During a job, she "heard" that the strokes of her employer's paintings were very similar to her lover in her previous life, but the other person was already a famous art master overseas and was full of inexplicable hatred for her. What she didn't know was that Gu Huaijin was also reborn in this life. He deliberately bought the house opposite hers and played her favorite cello in her previous life on the balcony every night, waiting for her to recognize his voice.
