those mijoo and babysoul shared lines are really them, if u listen closely u can hear babysoul kind of harmonizing with mijoo, and its sung by both of them live!!

and yes jin has no lines, but that's because she was absent in the song's recording...well she could've somehow recorded it idk

AND AGAIN jiae has the best part of the song that rap is just amazing lol (btw yes this is a remake because old one sucks lmfao)
