Carousel.

A blue-haired anime girl in a black and red outfit sits on a glowing red circular platform, smiling with glowing eyes, as the scene cuts to a brown-haired girl in a school uniform who kneels on the same platform, turns to face the camera with a hand to her cheek and an outstretched arm, then turns away, before the scene cuts back to the blue-haired girl. The setting is a dark, starry void with floating particles.
