In the movie "The Innocence of Dancers", the actors performed an elegant Latin dance. It is very difficult to practice this kind of dance, because what is needed is the perfect combination of the graceful temperament and graceful dance. In order to practice Latin dance well, Wen Genying spent six months! Before making this film, Wen Genying didn't formally learn to dance. His body is as flexible as ordinary people. After learning that flexibility is the foundation of dance, Wen Genying devoted himself to high-intensity training.

Wen Genying started with the most basic cheating and practiced dancing for ten hours every day for six months.

Keon-hyeong Park, who plays opposite her, was originally a musical actress with considerable dancing strength. She volunteered to be a dance teacher in Wen Genying and gave her "devil-like" training. Keon-hyeong Park even sat on Wen Genying's back, or pushed Wen Genying, who was practicing cheating, against the wall to "help" her practice flexibility.

The "little bride" who endured such pain finally developed the strength of a professional dancer and won the applause of the staff.
