A simulated text message conversation with a question that sparks curiosity: 'HOW DID WE NOT KNOW ABOUT THIS?'

The ad opens with a simulated text message conversation on a phone screen. The conversation progresses with messages about a discovery, followed by money symbols appearing. The scene then shifts to a grid background with text about cash back. The conversation continues with questions and answers about savings. The ad then shows a collage of various products, followed by specific items with sale percentages and a 'Plus Cash Back!!!' message. The conversation then shifts to a pink background with dots, where one person states they are 'stacking Cash Back on so many deals!!!'. This is followed by a meme of a monkey sitting on money, labeled 'I'M A SUPER STACKER', and a laughing emoji. The conversation ends with a question about being there and a response about downloading the app. The final screens show the Rakuten logo and a call to action.
