Su Wan, a doctor of medicine, crashed into the Shanghai beach in 1935 on a rainy night.
As soon as he opened his eyes, a gun was pressed against his temple.
In order to save her life, she was forced to perform surgery on Gu Qianfan, the gangster who was shot.
"Don't play tricks." He gasped and tightened his grip on her wrist.
The night the operation was successful, Gu Qianfan played with the aspirin bottle she took out from her bag.
"Ms. Su, this pill... Is more effective than the sulfonamides sold by foreign companies."
Neon lights flashed outside the window, and he suddenly raised his eyes:
"Stay and be my personal doctor."
"Otherwise, the whole of Shanghai will know that there is a female doctor of unknown origin..."
Su Wan looked at the photo of a Republic of China woman who looked exactly like herself in the mirror and fell into silence.
