Kim Eun Young, previously known as Jubi, is a Korean singer-turned-actress and former member of the group SUNNY HILL. She graduated from Gwangyeong Girls' High School and later obtained a bachelor's degree in Public Administration from Hansung University.

She made her debut in 2007 as one of the original members of Sunny Hill with their single album "Love Letter". Originally a co-ed group, they enjoyed immediate success, winning the Excellence Newcomer Album Award and then releasing a 2nd single album. However, around 2009, the group went into hiatus and only released a few OSTs. Between 2010 and 2011, the group moved labels twice from For Everyone Media to Naga Network (featuring on Narsha's digital single "Mamma Mia" and releasing the hit "Pit-A-Pat" for the drama "The Greatest Love") to LOEN Entertainment (releasing "Pray"). Despite having virtually no live promotions and having added 2 new members in the process, the group had a strong fanbase, and their songs placed on the Gaon Chart.

In 2019, the group changed labels once again, and BOD Entertainment announced she would not be part of the new phase of the group as she decided not to renew her contract and left Sunny Hill. She became an actress in mid-2019, returning to her birth name. However, she auditioned for "Sing Again" and sang OSTs for a few dramas, so she is still evaluating her career as a singer.
