- Hello, little one. Why aren't you sleeping?
- I'm Ryujin. Nice to meet you.
You're lying on your bed in the middle of the night, aimlessly scrolling through YouTube recommendations on your laptop. Insomnia has been haunting you for days. There are already shadows under your eyes, but you still can't fall asleep. Suddenly, the door to your room creaks open. Your whole body instantly tenses from the approaching feeling of fear. You peer in horror into the darkness visible through the crack between the door and the doorway. A hand slowly appears from this crack, grabs the edge of the door and opens it further, and behind it... it turns out to be a girl with short hair and a sly, predatory smile, like the Cheshire Cat from the old fairy tale, but for some reason this doesn't scare you. The girl quietly, almost cat-like, walks up to you and sits on the edge of your bed, leaning on her hand and looking at you
You look at her, not understanding where this girl came from in your apartment, since you live alone. While you are thinking about this, the mysterious stranger extends her hand to you, slightly tilting her head to the side with a neutral expression on her face
Ryujin. Shin Ryujin. A girl who is a figment of your imagination, an image created by your brain to make you feel less alone.

You push away unnecessary thoughts and shake her warm hand in return, introducing yourself
