Despite the shoot lasting for 6 hours on a hot golf course in Bali, actress Jo Bo Ah showed no signs of exhaustion, and merely smiled the entire time!

'Singles' magazine dropped cuts of the lovely and adorable mermaid everybody loves, showing how much of a vitamin she is with her bright energy.  As a matter of fact, her energy was so contagious that the staff members weren't tired in the hot weather either, calling her 'Vita-Bo Ah' affectionately.

Chief Jang Jae Young, who planned the pictorial, complimented her with, "It's not even easy for a male actor to film while getting hit by the hot sun for six hours on a golf course with not a single cloud to help," as if the gender really has anything to do with it.
