ZEROBASEONE member Han Yujin appeared on her first variety show. Han Yujin appeared as a guest on the YouTube web variety show "Hong Seokcheon's Jewel Box Season 3," released on January 6. On that day, Han Yujin was introduced as "the adult jewel who turned twenty this year" and showcased her variety show skills.

Han Yujin created a warm atmosphere by delivering a handwritten letter and gifts to MCs Hong Seokcheon and Kim Ddolddol. In the following jewel appraisal segment, Han Yujin's visuals and physique were highlighted. Her thick straight eyebrows, clear eyes, and prominent nose reminded the MCs of a pure romance comic, prompting continuous admiration.

Especially as the MCs actively responded, Han Yujin momentarily shouted "Mom!" which made the scene burst into laughter. Han Yujin expressed gratitude toward her members, saying, "As the youngest, the older members were very considerate." She also shared her thoughts on becoming an adult, stating, "I plan to show ZEROSE (the fandom name) a cute yet sexy side without holding back."

Han Yujin performed the mission song "Over Me" from the Mnet survival audition program "Boys Planet" together with the MCs. She showcased her presence with a deadly performance using a red scarf.

Meanwhile, ZEROBASEONE to which Han Yujin belongs will release a special limited album "RE-FLOW" on February 2. Prior to the album release, ZEROBASEONE plans to pre-release the album tracks and music videos twice on January 9 and 23, respectively.

This variety show appearance was Han Yujin's first challenge, and she captivated viewers with her natural charm and unexpected variety skills. ZEROBASEONE plans to communicate with more fans through future activities.
