Cute, cute!

A blonde anime girl in a school uniform stands before a dark door, smiling gently as sparkles float around her, then her expression shifts to surprise as she looks at a red-haired girl with a large, toothy grin, before the scene cuts to a close-up of the red-haired girl's face, then to the blonde girl looking down with a slight smile, and finally to a blurry shot of the blonde girl in a different setting.
