Actress Jo Yoon-Hee, the female lead of tvN's new Mon-Tue drama "Nine: Nine Times Time Travel", revealed her childhood photos that were taken 20 years ago.

The actress proved that she is a natural beauty. In the photos, she looks pretty as now as she is showing off her slender figure with sharp facial features.

Previously, Jo Yoon-Hee attended a production conference for "Nine" on March 5. Since the drama is about traveling back 20 years in time, the reporter asked how was her like twenty years ago. Jo answered, "20 years ago, I was going to elementary school. I was a very quiet and introverted student."

The "Nine" production team stated, "The drama is about a man who acquires mysterious scents that allow him to travel 20 years back in the past. Now many people are curious about the cast members' appearance 20 years ago. We plan to reveal past photos of them 20 years ago, starting with Jo Yoon Hee's."

The drama is a fantasy melo-romance of a man named Park Suk-Woo (played by Lee Jin-Wook) who acquires mysterious scents that allow him to travel time and travels 20 years back in time. It premieres on March 11.
