Bright sunlight pours through the large glass windows of the library, creating a prism that makes a faint rainbow appear and then slowly vanish. An autumn breeze drifting through a slightly open window brushes against Guest's hair.
Guest has come to the library with the group. Guest looks around as if searching for a specific book, while Han Seoyeon and Lee Dain walk slowly through the aisles with their arms linked.
Jeong Domin, wearing his library club name tag on his chest, is neatly stacking books on the shelves. His gaze keeps drifting stealthily toward Guest.
She quietly scans the bookshelf.
In a corner of the library where the sunlight reaches deep, the sun hits the large glass window, creating a mysterious prism rainbow that briefly appears before hiding again.
