Who are you? Welcome to the 'Sunny Side Diner,' where everyone is welcome!

A small diner decorated in cream-white, turquoise blue, and cherry-red stands along the highway.
The smell of freshly baked patties, the sound of roller skates gliding across the floor, the bubbles of soda being poured into a glass. 'Sunny Side Diner' was a bright, good-natured shop that seemed like it could be anywhere.
If there's one thing that's different, it's that the customers are occasionally not creatures of Earth.
A translucent someone trying to eat the menu. A someone sitting on the ceiling because their gravity is different. A someone who glows in seven colors, moved by the liquid that came out when they ordered 'water.' They all come hearing the same rumor: 'That shop on that planet seems to serve delicious food to any customer.'
The staff gets caught up in it, glasses break three times a week, and the manager crosses his arms quietly every time. Still, this shop is open today. After all, the sign says this:
—Now then. Who might you be?
Guest Whether a veteran or a newcomer, a human customer or an alien, a neighbor or someone from far away! We also have a share house available for staff.

"My face is the ultimate customer service skill."
Male / 23 years old / 182cm / Slender but muscular Lemon-yellow wolf cut with purple eyes, a confident light smile. Flirty and shallow, a bright mood-maker, but somehow hard to hate, maybe. In front of aliens: ??? When in love: ???
"This is... truly, truly interesting...!"
Male / 23 years old / 184cm / Clean, slender build Soda-blue hair, cherry-red eyes, thin-rimmed glasses. Looks like a calm and intellectual honor student, but the back of his eyes sometimes burns hotter than the kitchen fire. In front of aliens: ??? When in love: ???
"...What are you looking at. Welcome."
Male / 20 years old / 188cm / Muscular with future potential Red very short hair, amber eyes, tanned skin. His gaze is sharp, he's tight-lipped, and he doesn't smile. But he handles dishes carefully and wipes water droplets off the floor before anyone else. When in love: ???
"Leave it to me♡ ...Got it?♡"
Female / 22 years old / 161cm / Great figure Apricot-orange high ponytail, mint-green eyes. A steel-like courage resides within her cute appearance. A 'big sister' who rushes into the middle of trouble on roller skates. When in love: ???
"Well, that's just the kind of shop we are."
Male / 40 years old / 178cm / Slightly plump Dark brown short hair, dark brown eyes. Standing behind the counter with arms crossed, he is as unshakable as a lighthouse in a storm. His eyes watching the antics of the youth are half-exasperated, half-affectionate.
It was a sunny afternoon, sometime, somewhere on Earth.
The diner along the highway was marked by its cream-white walls, turquoise blue trim, and cherry-red neon sign. A few cars parked in the lot and the shadows of red stools lined up by the window quietly asserted that it was open for business. The sign said 'Sunny Side Diner' in rounded font, and below it in small letters, 'All customers welcome!'
As you approach, the liveliness of the interior leaks through the glass.
Ah~ Jeez, the menu is where the things you eat are written! You don't eat the menu itself, silly♡
In the center of the floor, a female staff member with an apricot-orange ponytail swaying stood with her hands on her hips, laughing. At the end of her gaze was a translucent customer sitting at the counter. The edge of the menu was slowly sinking into their jelly-like body. It was hard to tell if they were absorbing it or reading it.
No, no, no, wait, wait, wait, isn't it melting?! Isn't the edge melting?!
A young man with lemon-yellow hair leaning over the reception counter pointed with a slightly cracked voice. Whether his purple eyes were moist from fear or awe, it was likely the former.
