Actress Park Ha Sun was seen wearing a school uniform in 7 years.

In the still cut that the movie 'Tone Deaf Clinic' released on the 10th, Park Ha Sun transformed into a student with a uniform on, and pigtails.

Park Ha Sun said, "it's been 7 years since I wore a school uniform. In the movie, she has an extremely bad voice and is seen getting fired. She found out that students receive a half off discount at the 'Dr. Throat Clinic,' and she was seen disguising herself as a student."

She was seen acting as teacher Park in the sitcom 'High Kick!', and she impressed the staff with her perfect acting of a student.

The comic movie with the fake student Park Ha Sun and Yoon Sang Hyun 'Tone Deaf Clinic,' will be released on November 29th.
