Why it worked
The video likely performed well due to the visually appealing aesthetic of the individuals and their formal attire, combined with the elegant setting of the escalators and chandelier. The use of popular personalities (indicated by the hashtags) would also contribute to its reach.
Summary
Two individuals, presumably Suran and Naran, are featured on escalators. They are dressed in formal attire and appear to be posing for a photo or video shoot, with other individuals in white dresses also present on the escalators.
