The singer will be taking on the role of Kwon Bo Young, a screenwriter who works closely with Lee Sun Gyun and who will also often appear as the "too-busy-working-to-take-care-of-myself" workaholic. 

The staff relayed about BoA, in addition to revealing some behind-the-scenes cuts, "Her will is amazing. Even during our script reading last month, she had 8 episodes worth of the script completely memorized. Please look forward to Kwon Bo Young, who will be showing off as many qualities as she's preparing for."
