Huang Jiawen (played by Angelica Lee), who has been blind since childhood, underwent corneal transplant surgery and can see things around her, but she also fell into endless troubles. She found that in addition to being able to see normal things, she could also see ghosts that others could not see, which seriously interfered with her life. Jiawen even wished she had never seen it. Yingying, a little girl who lived in the same ward, died during the operation. She came to say goodbye to her and watched Yingying leave. Jiawen therefore understood the benefits of "yin and yang eyes": being able to see the people she wanted to see. When she finally calmed down and was ready to accept her "difference", she was horrified to find that what she saw in the mirror was not herself, but another woman.
