At the beginning of the Music Video, Sooyoung and Jessica were playing a game of cards. Seohyun and her friend caught her friend's boyfriend with someone else. Seohyun is seen comforting her friend and it moves to the usual-box set and the music plays. Seohyun sends a text to Tiffany about him and Tiffany gets it immediately. She then shows the text to Hyoyeon and walks up to sit on the table beside where the boy is sitting. After that, all members start to punish him.
