Judging by it being a 2 parter im guessing its another deep lore video. Based on a theory another poster made and my own observations heres what i think is going on. I'll try not to be too long. But before i go on a long winded one.. in a nutshell.. Hyein doesnt exist as a physical form but a supernatural entity.. now lets go on lol ..... NewJeans Minji, Dani, Hanni, Haerin and the 'guy' could be paranormal phenomena investigators... investigating the strange goings on in the city.. the odd weather.. theres a UFO.. Zebra Unicorn.. they get out of a strange looking possible investigation type van at the start. None of those Members Interact with Hyein aka the bunny throughout the whole video.. it seems only the guy sees her. Minji comes to get the guy in a sort of lets go motion but it seems she doesnt see or realise Hyein is there. Even when they are dancing Hyein aka the Bunny shows up and dissapears again continuously. The bunny reminds me of Frank the Rabbit (a supernatural being) from Donnie Darko.. in that film only Donnie could see frank the rabbit... much like it seems only the guy can see Hyein in this... the lyrics suggest it might be about a 'supernatural' relationship between the boy and hyein. The dancing scenes also flip from 80s looking to current modern times with them wearing current clothing holding smartphones 2:59. Donnie Darko was also about time travel. Theres a scene if you pause quickly where Hyein is sitting to left of the screen looking ghostly holding an alien toy 5:47. Its possible Hyein is the Alien from the UFO and the bunny is her real form.. with Hyein being her human disguise that for some reason only the boy can see.... theres more but i dont want to be too long winded and till we see part 2 :P
Hyein injured her right foot. She is currently able to walk, and although she will not be able to dance on this stage in Japan, she is expected to return to the stage around July.
