For actress Park Shin Hye, a promise is a promise. The 26-year-old kept her word of honour and mesmerised her fans with some incredible dance moves at Naver's V Live app.

Shin Hye, who plays the female lead in new drama Doctors, committed to her fans she would offer a special dance performance of TWICE's Cheer Up if the viewer ratings of the medical inspired drama surpassed 15 percent. As the rating of the episode aired on June 28 shot up to 15.6 percent, the actress's agency affirmed the live broadcast of the dancing gig.

Keeping her words, the Pinocchio actress presented an adorable performance on July 12. She was accompanied by her co-star Moon Ji In, who plays her best friend in the drama. The girls also gave a small tour live from the sets of Doctors.

While Doctors is doing exceptionally well on the rating chart, Park Shin Hye never thought her drama world be a huge hit. Infect, the actress was well prepared for the flop. "We thought the timing [of this drama] would lead to a failure. How would we land a successful drama every single time? So we were prepared for failure, and told ourselves not to be disappointed too much if the drama didn't do well," Shin Hye's agency told soompi.
