A B C D

A young anime girl with brown hair and a black hoodie appears in a series of short, looping clips. She begins with a blurry, glowing effect, then winks and gives two thumbs up with stars around her. The scene cuts to a red square and a row of blue letters, then shows her with a confused expression as the text "你谁啊?" (Who are you?) appears. She then looks tired, scratching her head with the text "辛苦了" (You've worked hard), and finally stares with wide eyes and a small smile as red text flashes at the bottom.
