Black and White Impermanence Competes with Emergency Doctors for Heads

Bai Wuchang and Bai Ling travel between Yin and Yang with his brother Xuan Ye every day, and stage a soul-grabbing battle in the emergency room. In an accident, she discovered that the cold and aloof doctor Xie Qingheng could actually see her. From then on, she had a lot of fun as a ghost, secretly sitting on his desk and eating candied haws, causing trouble during his surgery, and sneaking close to him when he was sleeping. But Xie Qingheng, who seems indifferent, can always accurately catch all her naughty tricks. When the boundaries between yin and yang gradually blur, a love that spans life and death quietly sprouts. They will face the test of different paths between humans and ghosts, and will also write a romantic legend that has never been seen in the underworld.
