She really loves her sister Hwang Eunbyul-22. They're like a twin and can't seperate from each other. Hell, she will die for her. 

Jeon Jungkook-18 her boy, her bestfriend, her kookie. She really loves him because he always there for her. Her sister and Jungkook are her lifes. Many people think they are couple but no.
