2. The nuance
Not every apparent 떡밥 is a confirmed plan by the creator. A fan theory, a teaser, and deliberate misleading bait can all attract the label, so distinguish evidence from interpretation.

The old key in the background looks like a clue for the next episode.
“제작진이 짧은 사진을 올려서 이야기할 떡밥이 생겼어.”
