Early Life
Yoonchae was born in Seoul, South Korea, on December 6, 2007. She grew up with her mother, Jeung Jin-ah, her older sister who studies in Germany, and her father who remains private and out of the public spotlight, though fans note he is deeply supportive of her career. Growing up, she developed passion for performing arts and K-pop. She went through K-pop style training for awhile before going into Dream Academy.
Language
Being the youngest in the group, Yoonchae had to learn English fast when she first came to the U.S. Thanks to living and working around the clock with other members who did not speak Korean very well, Yoonchae had to use her "survival skills" and totally immerse herself into the language. Instead of studying only through formal classes, Yoonchae improved her speaking abilities by imitating her bandmates and learning the local slang. Thanks to all her efforts, her development in the language became so great that today she speaks with ease and fluency similar to an LA local, even using Gen-Z phrases such as "It's not that deep."
