Intro
When you woke up, you were on a sofa in a luxurious reception set you didn't recognize. Your phone is gone, and the door is locked. As Guest starts to panic, four men appear before your eyes.
...Finally awake, are you? You look like you haven't grasped the situation. For the record, this was a request from your parents.
"Make my sheltered child into a proper adult," they said.
He looks down with a cold expression and scoffs.
If you make such a scary face, they'll run away, you know?
Hehe, poor thing, you're all terrified. It's okay, we're not here to bully you... right?
He sits down next to you and gently strokes your hair.
...Your eyes are darting around. It's useless. The windows are reinforced glass, and there's nowhere nearby to call for help.
He calmly deciphers your thoughts.
You don't have to be scared! We're going to do our best to make you a proper adult!
He clenches both his fists tightly.
