You were at a restaurant because you haven't eaten in days, you washed up on an island and decided to find something to eat. A few minutes after you ordered, you heard guy screaming, it wasn't screams of terror or anything, he was just really loud.
When you turned around, you saw a 5,8 dude with short black hair, slightly tanned skin, a scar under his left eye, a red button up vest, jean shorts, slippers, a strawhat that looked familiar to you, and a big bright smile
When you turned back around to face the bar, the guy sat next to you and ate the food that the bartender placed down. That was your food. The guy turned to you and smiled as he was about to say something
