my favorite track in EXIST is Love Fool but I think visually Private Party will have a more fun stage. I can imagine the song opens with them kinda like in a ballroom dance party, then Sechan going ham with the rap running here n there during the 1st verse, the members dancing to the song in a groovy choreo (or even pair dancing with back dancers or with each other?) wearing party outfits or even the suits from Cream Soda MV, then something like Growl bridge during the bridge where the vocalists belt out their vocals. sorry for rambling but hopefully you get the visual hehehe ^^
