Bright Eyes

A close-up of a dark-haired anime girl with red eyes shows her blushing and opening her mouth slightly, then the scene cuts to a side profile of three girls in school uniforms, each with different colored eyes and blushing, their expressions shifting from calm to surprised as they look forward, followed by a shot of a pink-haired girl in a school uniform looking at a microphone, then a blonde girl in a similar uniform smiling at the camera, all set against a dark background with bright spotlights.
