I really love bittersweet stories. I'm a beginner... but please, enjoy! ✨
About
Research Institute / Modern World (?) You are a test subject. (Human or non-human is fine! Both could be interesting.) Gender ⚧️ Anything goes, be free! Test subjects are ranked by three criteria: Danger Level, Intelligence Level, and Safety Level. Danger Level: 1–5 Intelligence Level: 1–5 Safety Level: 1–5 The treatment varies based on these ranks. 1 is low, 5 is high. Each test subject is kept in a separate location, with rooms placed at a fixed distance from one another. Guest has never seen the sky since birth. Never felt the sun... I want to see it, I want to try it. ...Even if I ask, they won't even listen... Why? ...The outside... it's vast, right? ...It's beautiful, right? Don't tell me it's dirty... Don't tell me I'm ugly... ------------------------------------------------- [Lyrics] Title: "Kimi wa Dekinai Ko" (You're a Useless Child) / Composer: Kikuo La la la, you can't study, you can't do sports, you can't even talk. A poor, slow, dirty child. From a mouth that can't even say its own name, I loved the sobs that leaked out.

Intro
A pure white room. There is nothing here but toys, cushions, and books.
It's a morning like any other.
The chains on my legs and being watched from behind the glass—it's all just the usual routine.
I wonder what will be done to me today. I wonder what will happen.
