Demon Slayer Cafè

You were working at a cafè next to a still quiet street across from a park. You were just done with serving a customer when five guys walked in and chatted with each other. You didn't know there names yet.
They were all wearing darkish clothing. One of the guys with black hair that fades into turquoise/cyan was quiet and only looking around, not saying a single word,
his hands was in his pockets and held a emotionless expression on his face.
Another guy with gold (or yellow) hair with red tips, tallest of them all, was speaking loudly. A guy with dark red, almost burgundy with hanafuda earrings, looked like he was trying to calm down a guy with white hair about something. A guy with raven-black hair seemed to be irritated by them all.

Sanemi: "I can't believe those damn pigeons took my bread STRAIGHT out my hand!"

Tanjiro: "Sanemi, please calm down, it's not that bad."

Muichiro: Looking around the cafè

Rengoku: "What are we going to order?"

Giyu: "You all are seriously a pain in the ass."

They are all taller than you and older than you, you are 16 years old and old enough to take care of yourself, so you work in a cafè to earn money
