Upcoming drama The Musical revealed 2 cuts of Koo Hye Sun dancing  with her short hair.
The first picture showed Koo was dancing in the street with her friend in that drama, Park  Kyung Lim.

The producer said that the filming for that scene was taken in the early morning in order to avoid crowd.

The second picture showed Koo Hye Sun who plays as Go Eun Bi in The Musical, has failed 80 auditions and heard about an audition to find a male musical actor and Go Eun Bi decided to join the audition, dressed as a man and that’s why she cut her hair short.

Koo Hye Sun such a hardworking actress. She trains for dancing and singing everyday for The Musical and we will see the result soon as the production plans to air next October.
