I'm already world building just based on these two images:
Much like many teenagers, a group of friends love pizza, and one particular pizza shop in town has the best pizza they've ever had. However, they instead usually order from other shops, even if they're greasier, have burnt crusts, and lackluster toppings. It's too far to walk, the roads too busy with traffic to safely cross on foot or bike, and they're not old enough to drive; the only way to get the divine pizza is to call for delivery.
When they're daring or desperate enough, they accept that they must play Delivery Roulette. They know the shop has four drivers on staff during the times they would normally call. Three of them are fine, just meek and pimply teenagers like themselves just trying to make some honest spending money.
It was the fourth driver they dreaded: The Pizza Girl. While she was more beautiful than any of the girls in their class, smelled like fresh fruit and flowers, and drove the most amazing car they've ever seen, her temper was shorter than the boys' attention spans, her attitude more rotten than the trash they assured their parents they took out, and her words stung harder than a whole hornets' nest.
The friends would tense whenever they heard her car in the distance. They scrambled to decide who was unfortunate enough to answer the door, fighting as if their very survival was on the line. They once tried leaving a note and money at the door, but they couldn't avoid her ire as she banged on the door and shouted for someone to take the pizza. Another time they tried answering the door together, thinking there would be power in numbers, but it only seemed to amplify her power; the boys spent the rest of the evening in stunned and heavy silence.
Whenever their classmates would rave about the pizza shop, the boys shuddered and asked how they handled The Pizza Girl. Half of them said they'd never encountered her, while the others said the rare time she showed up she was only terse, cold, and quiet. The boys tried to explain their encounters, but no one seemed to believe them, and thought they were exaggerating when they said she arrived more often than the other three drivers combined.

The Pizza Girl hated her job. The hours were terrible, the pay was garbage, traffic caused her to barely meet deadlines, and her customers were often rude and ungrateful. She tried applying elsewhere for work, but they always hired those saccharine and obnoxiously perky girls covered head to toe in pink and lace.
But there was one silver lining to this immense gray cloud: delivering pizza to three timid boys on the other side of town. They didn't call often, but when they did she would "persuade" her fellow drivers to make the delivery. They reminded her of her little brother, and she couldn't help but tease them whenever she saw them. She knew she could be a little harsh with her sarcasm, but their reactions were funny, and she knew that it would toughen them up against others' harsh words in the future.
