After placing fourth on the wildly popular girl-group–making survival show, Produce 101 – think Making the Band but 101 times bigger and more intense – a star was born in Chungha. As per the premise of the show, she cut her teeth as part of 11-member girl group I.O.I for a year. Yet Chungha's sharp dance moves and sophisticated presence would set her apart from the others, earning her the nickname "Dance President." Now that she no longer has to share the spotlight, we can bask in the full range of her charms. In her latest single, "Roller Coaster," Chungha's supple voice simulates the ride, rising, falling and looping with ease.
