Without her

A pink-haired anime girl with red eyes and a red uniform appears in a series of shifting scenes, beginning in a dark, confined space, then shown in a bright room with a boy, followed by a close-up of her face, a shot of her lying down, a glowing full-body view, and ending with a close-up of her face as she looks forward. The setting transitions from a dark interior to a bright, possibly indoor environment with windows.
