Kim Joo-na, stepsister of hit actor Kim Soo-hyun, is set to make her solo debut as a singer next year.
Her agency Keyeast Entertainment told a local media outlet, "It is true that Kim Joo-na is his stepsister but she seems to have no contact with him."
The 22-year-old Kim Joo-na recently received attention after singing the OST "What Do I Do Without You" in SBS's drama "Upper Society."
She was once a trainee preparing to become a member of The Ark, a girl group from MusicK entertainment, which made its debut in April 2014. She later changed her plan and decided to be a solo singer.
