I don't know, nan molla comes from the lyrics of a song called Fake Love made by South-Korean KPOP idol group called BTS. The romanized lyrics of the song say "Why you sad? I don't know, nan molla." If you ask any ARMY or BTS fan why they are sad, they will probably say nan molla.
Person 1: "Why are you sad?"
