I am a MESS

A young woman in a light blue dress stands on a balcony overlooking a city at night, her hand resting on the railing as glowing blue lines float in the air around her. The scene cuts to a close-up of a different girl with brown hair looking up with a concerned expression, then to a bright flash of light, followed by a close-up of a girl with black hair smiling gently as a white heart appears beside her, and finally to a close-up of a purple eye reflecting light.
