The initial text message: "GIRL. I have a shopping secret for you! 🤫"

The video simulates a text message conversation on a purple background. It starts with one person telling another they have a shopping secret. The second person expresses excitement and asks for details. The first person reveals that the secret is earning cashback while shopping. The conversation then shifts to guessing what 'CB' stands for, with various humorous suggestions like 'Coffee Break' and 'Chicken Broth'. Finally, 'CB' is revealed to mean 'Cash Back with Rakuten'. The ad then shows logos of popular stores and asks about the sign-up cost, stating it's free. The ad ends with a clapping animation and the Rakuten logo.
