Are you in chains?

A young woman with long blonde hair, wearing a school uniform, holds a red apple and looks at the camera, then turns and walks away from a building with a "CHESUT" sign. The scene cuts to her in a red dress, stretching her arms behind her head, then taking a selfie with a phone, and finally, in a kitchen, using a piping bag to decorate a cupcake. The final shot is a close-up of her hands adjusting a large red bow on her school uniform.
