They just left

A white-haired anime character is shown in various states of distress and contemplation, including hugging her knees and covering her face, before the scene shifts to a small, round creature with a camera lens for a head pushing a stack of books, then to the character running away from the camera into a blur of lights, followed by a close-up of a sealed envelope, and finally to the character smiling gently while sitting in a room with a window.
