A black-haired anime girl with large eyes looks forward in a dark setting, then the scene cuts to a close-up of her face as she is kissed on the cheek by an unseen person, followed by a shot of a blonde girl playing a guitar, then a blonde girl in a hoodie playing a drum, then a dark-haired girl sitting in a bright yellow-lit room, and finally a close-up of her face as she looks down with a sad expression.
