Both about kidnapped girl. Higashino is more satisfactory because it's about revenge.

Revenge story about a lady is kidnapped a nd assaulted by three dudes.

same story

In both films a woman is treated like a slave. She starts a romance with a villager.

Both chicks in these films have absolutely no rights and are sold for the use of village men.

-Women's rights
-Slavery
-Woman sold to multiple men
-Chinese mountain house (idk lol little hut on a mountian)

A woman is sold and forced to marry a man in a remote Chinese landscape.

Both films are about a sad break up initiated by the girl.

Women are abducted by psycho and held captive. Some are murdered.

Disaster movies. Mysterious element. Moral ambiguity.

Korean disaster movies. Survival, mayhem, and ambiguous morals. Largely takes place in a building.

Both are BL office romances between a director and an employee.
