This is a possible concise summary:
The text is a transcript of a video where six members of NCT 127 play a game called "Heavyweight or Lightweight". The game involves chatting online and trying to guess who among them can drink the least amount of alcohol. The Lightweights have to pretend to be Heavyweights and avoid being exposed. The Heavyweights have to spot the Lightweights and vote them out. The text shows the first three rounds of the game, where Red Cap (Jungwoo) is revealed to be the Lightweight. He tries to act like a good drinker, but his answers are too vague, outdated, or inaccurate. The others tease him for being a boomer and having aegyo. He also has to sing "A Shot of Soju" as a punishment. The text ends with them taking photos like Heavyweights.
