Bae's glow up

A young woman with long hair appears in a series of close-up shots, first making a wide-eyed, startled expression, then opening her mouth in a scream, followed by sticking her tongue out playfully while wearing sunglasses, and finally smiling while running her hand through her hair. The scenes transition between different settings, including a room with a wooden door, a wall with posters, and a plain background, with the final images in black and white.
