What the Park Family Story Teaches Us

A Guri Korean family. A younger sister. A childhood that began at JYP at age 8 — the longest training period of any TWICE member. A solo album that broke the K-pop female-EP record on Billboard 200.

For every family — large or small, famous or otherwise — the Jihyo story carries the same lesson. Some children begin training before they turn 10. Jihyo's 2005 JYP joining at age 8 is on the Park family record alongside every TWICE record.
