Girl I know.

Two anime girls in school uniforms, one with long pink hair and the other with short blonde hair, stand face-to-face in a dark, starry setting with falling petals, slowly leaning in to kiss as the background shifts to a vibrant nebula, then the scene cuts to a close-up of a third girl with black hair and red eyes, followed by a shot of a boy and a girl in school uniforms running forward with bright light behind them.
