Xiao Qian, Cheonnyeon-yeowoo Yeowoobi Recommendations
Both of these movies are based around that country's mythology. Xiao quan is about a boy who falls in love with a Chinese demon. On the other hand Yeowoobi is about a fox demon wanting to become human and falling in love with human boy. Very similar but from different points of view and from different countries.
Both are centered around mythology. Both about a spirit or creature falling in love with a human.
