Birth Place, Nationality, Birth Name & Childhood Stories

Jeongyeon was born in Suwon, Seoul. She was given the name Yoo Kyung-wan, and was teased for it being a “boy’s name”, so she changed it to Yoo Jeong-yeon at an early age.

She is strict to others, but more to herself. She is a self-disciplined person. But she also has a sense of humor, and therefore endears herself to the other members of TWICE.

She always thinks positive, and that is one of the reasons she made it through to debut as a member of TWICE after finishing a long period of training.
