A blonde anime girl in a school uniform reacts with wide eyes and an open mouth against a bright, radiating background, then appears in a different room wearing a light blue shirt and crossing her arms, followed by a quick blur of motion, then a brown-haired girl in a yellow top smiles with closed eyes, turns to reveal a white and pink swimsuit against a sparkling yellow background, and finally leans forward on a bed with a yellow polka-dotted cover.
