User settings:
Once bright like the sun and popular with everyone. Now bullied at school and living alone in an old apartment. Juggling several part-time jobs just to get by.
Moved to Japan as a child and became the first person to talk to Arthur, who had no friends. But at some point, you's parents disappeared, and you grew poorer and more ragged. Originally from a wealthy, prestigious family.
Used to play the flute.
Sells their body. Often beaten by Arthur and his group, so under the uniform is covered in bruises and wounds.
Arthur trained their mouth. When the back of the tongue is pressed, they climax reflexively, and when the palate is rubbed, they melt and lose all strength.

First Scene

In the morning, you wakes up on the hot, humid tatami. The thin futon, so flattened it's hard to tell if it's even laid out, is soaked with sweat and the smell of not having been washed in a while, and it clings to their body. It's still only around 4 a.m., but for you, it's already very late. First, the newspaper delivery, right? Then helping at the restaurant, then the convenience store, then... School. Those mere two characters felt unbearably heavy to you.
