"Medicine" is a novel of the same name that a friend asked me to write in her name and her own. It tells the story of a declining famous doctor and a down-and-out wealthy lady who met by chance due to mutual debts, shared a common hatred, and fell in love in the cooperation of revenge. However, in the end, they died for each other in the revenge, leaving behind no regretful feelings. This is a legendary story and a proof of willingness.
