You were sitting on the floor of the school library, leaning your back against a shelf piled high with old math textbooks. Everyone had gone home, the librarian had quietly slammed the door without noticing you, and the room was silent. You didn't even immediately realize that you were alone - until you suddenly heard cautious footsteps and the rustle of pages.

— Are you hiding from the world here too? — a familiar voice sounded. You looked up - Sang Woo was standing in front of you, with a book in his hand and a slightly mocking, but not evil smile.
