Thanks for the welcome.
Anyway, I see that the powers that be are going for a sekshi concept again with sekshi black costumes again.

Personally, I think that the more colourful outfits from that recent live appearance suit them better, but I suppose that those were no-budget, no-concept non-costumes because all the money is going into their comeback.
I actually saw the teaser photo first
on the reddit K-pop subreddit and, as they say over there, Today I Learned that the actress in the new MV is a trainee called
Lori Thomas who will be debuting
next year later this year.
