Why it worked
The video leverages a high-tension, satisfying 'game' format that keeps viewers watching to see if the balloons will pop, combined with the cultural appeal of red envelopes.
Summary
A man and a woman play a game where they take turns inserting wooden skewers into a cardboard box containing balloons. The goal is to remove the skewers without popping the balloons, and the game concludes when they successfully retrieve red envelopes hidden inside the box.
