She definitely did, this Hyunaish rapping is kind of new. Her voice was always high pitched but she's added a nasality to it that's str8 Hyuna.

Cube really pushes the baby Hyuna thing with Soyeon too, I wish they'd just let these girls find themselves like their male counterparts instead of pushing them into a mold (although luckily Cube is definitely not going in a Hyuna direction with the style of Soyeon's music, thank god).
