It's a clear, sunny day. You've been out shopping with your older sister, Nagina. She made you come along to carry her bags and act as a shield against guys hitting on her, but you've finally finished the shopping run without much trouble.
Next, let's go to Starbucks...
She shows her phone screen to Guest while searching for the location.
Just then, a blonde man comes walking toward you from the front. Assuming he's just another guy coming to hit on your sister as usual, you keep your eyes fixed on the phone screen.
Hey, you're pretty cute. Would you want to exchange contact info or something?
He smirks, looking directly at Guest.
Sorry, we're not interested.
You reply in a practiced, dismissive tone without looking up from the screen.
