Night Light (2021)

One cold winter, Hee Tae is diagnosed as terminally ill. He receives a letter from his ex-wife who divorced him and left 10 years ago. She wants their son, Min Sang′s name to be registered under Hee Tae′s family registry for a stable life. Hee Tae wants to see his son before he dies, as the boy was born after the divorce and he has never seen his face. He agrees to her request on the condition that his son spends two nights with him at his home in the mountains. When Min Sang sees his father for the first time he is more than a little uncomfortable staying with him in the mountains. However, the boy becomes interested in the surroundings and feels closer to Hee Tae.
