Modern Line
Actor: Xu Yan (graduate student of medical school)
Heroine: Xu Qing (sister with congenital heart disease)
Republic of China Line
Actor: Lin Jingyun (Republic of China Surgeon)
Heroine: Su Yun (music teacher/"Yun Niang")
The two pairs of characters form an exquisite mirror relationship:
1. The echo between medicine and music - Xu Yan/Lin Jingyun (physician) and Xu Qing/Su Yun (music bearer)
2. Protecting and being protected - Both pairs of relationships are brotherly protective (Xu Yan to his sister/Lin Jingyun to Yun Niang)
3. Destiny reappears - Xu Qing and Su Yun have the same illness, the same snowflake birthmark, and the same dream
Special attention should be paid to:
- Xu Qing and Su Yun have some kind of supernatural connection (maybe reincarnation or blood inheritance)
- Although there is no direct hint of blood relationship between Xu Yan and Lin Jingyun, they have formed a spiritual inheritance through medical notes.
- The real "Snow Festival" ceremony is actually completed by two pairs of men and women (an intertwining of modernity and the past)
