Perfect

In a library, four identical cartoon girls in blue dresses stand in a line, holding up a stack of four gray cards with the Korean character '이' on them, then flip them to reveal a picture of a green vegetable, while the text "One! Two! Three! You" appears at the bottom. The scene cuts to a cartoon character in a boxing ring, wearing headphones and red boxing gloves, who punches a brown punching bag that swings back and forth, with the text "Go for a Perfect!" in the top left corner.
