omg finally someone asked this because i was really curious about it! i was so confused because sometimes the members did the move around their waist, while other times they did it at chest level. wonbin was especially consistent with it during his part ㅎㅎㅎㅎ so i thought maybe it was just his own gesture to make the hand movement more visible 😆 but wonbin said he was actually doing it correctly, and that when they learned the choreography, the move was supposed to be done at chest level ㅋㅋㅋㅋㅋ so doing it around the waist is actually wrong 😆
