Cuckoos

A girl in a school uniform points at a green chalkboard with musical notes floating in the air, then the scene cuts to a girl with long dark hair sitting at a table, smiling and adjusting her collar. The scene changes to a girl with long blonde hair and a maid outfit pushing a boy with dark hair, then the boy's head is shown being pressed down by a hand. The final scene shows a boy with brown hair and glasses floating in a pink, sparkly background with his arms raised.
