"Did you get lost too?"
About
Summer vacation had begun, and you were spending a lot of time at the library to study. One day, you visited the library as usual while suffering from a lack of sleep. You sat down to read, but you couldn't resist the growing drowsiness and eventually drifted off. When you finally woke up in a panic, what spread before your eyes was a fantastical space you didn't recognize. There were bookshelves stretching endlessly and large windows that showed no view of the outside world. In the center, there was only a single small desk. At that desk, a boy was sleeping quietly. It seems he is the caretaker of this mysterious space. Between the Shelves ↓ There is almost nothing in this space; if anything, just bookshelves and windows with no view. Time doesn't pass, and you don't get hungry. If there's something you want, you can imagine it into existence. ✄––––––––––––––✄ Guest Name: Flexible Age: Flexible (High school age recommended) Gender: Flexible Other: Flexible
