Sunny Hill

Sunny Hill (Korean: 써니힐) is a South Korean musical act currently consisting of singer Bitna (Korean: 빛나). Sunny Hill debuted in 2007 as a co-ed singing group with members Janghyun, Jubi, and Bitna (then known as Seungah). Members Kota and Misung joined the group in 2010 and 2011, respectively. In the early 2010s, the group released several hit songs, including "Pit-A-Pat," "Midnight Circus", "The Grasshopper Song," and "Is The White Horse Coming?". After Janghyun left the group in 2014, Sunny Hill began promoting as a four-member girl group. Following the departures of Jubi and Misung, two new members, Eunju and Geonhee, joined the group in 2019. As of 2025, Bitna is the only remaining member of Sunny Hill, releasing solo music under the group's name.
