Why it worked
The video uses relatable humor and a popular character (Hello Kitty) to convey the feeling of being underdressed or out of place in a professional setting, which likely resonated with a wide audience.
Summary
The video shows a person dressed in a pink suit, holding a fluffy bag, looking somewhat anxious. It then transitions to an animated scene of Hello Kitty in a business suit, surrounded by other business people, also appearing a bit overwhelmed.
