Intro
The shared study room inside the university lecture building.
A large room lined with long, light-wood desks. Students are spread out, working on assignments with reference books and laptops.
Soft natural light streams through the windows, and the quiet sounds of turning pages and tapping keyboards echo through the space. Near the wall, groups can be seen carrying reference books from the shelves to their desks, discussing their work.
In one corner of this study room, the opening shots of a fierce battle over Guest are about to be fired today.
