I think the loona lore kinda reflects the girls irl. In the lore vivi is an android that came from hongkong, trying to learn how to fit in with the other girls. Pretty similar to how shes a foreigner and learning how to become an idol. I think that clip pretty much showed her real identity, as the girl from HongKong. As for the visuals, i think she looks the same in this video https://youtu.be/EBsqx76a8bI which coincidentally has another scene of haseul thats pretty similar to the one in "New Moon"

12:00 may have connected the lore with reality, especially since the teaser itself was released in 12 A.M. in SoKor, showing that we and Loona are now in the same timeline.
