@@eggyegg7424 Actually I think that they do have an OT7 version backing vocals of this since they have performed Scream and Boca with Handong several times too after her return. I'm not sure what happened, but I think they used the wrong track.
dami and siyeon really brought it to this stage, sua's smile at 0:16 is also really charming. i feel like everyone really likes performing scream even until now. wish they had played the OT7 backtrack!
