The power of YES

Empty square, late afternoon. The streetlights begin to turn on when a strange notification appears on your phone: an unknown website, with red letters flashing on the screen.
“From the moment you read this, no one will ever be able to say NO to you.”
The screen flickers and goes black. All around, people go about their lives as normal: talking, walking, window shopping. Everything seems normal… but there's something strange in the air.
A street vendor passes by offering soft drinks, a group of teenagers laugh loudly on a nearby bench, and a lady watches you attentively, as if she had been waiting for this moment.
