Choi Soo-young, a member of the popular K-pop girl group "Girls' Generation," has been cast in a KBS TV soap opera aimed at improving the perception of physical disabilities, the network said on Monday.

The terrestrial network said the 26-year-old singer will appear in "Perfect Sense," a one-off special show produced to enhance the general public's understanding of the challenges and social prejudice faced by handicapped people.

"Perfect Sense" is the 8th in an annual series of co-produced TV drams by the Ministry of Education, Samsung Fire & Marine Insurance Co., and a local advocate group for the disabled.

The story centers on a girl, Eun-seo (Jung Chan-bi), who is slowly losing her eyesight but remains positive after meeting a blind teacher Ah-yeon (Choi Soo-young) and an aging guide dog.

All of the cast appear on the show as unpaid volunteers.

It will premier on KBS 2TV at 1 p.m. on April 20, the country's Persons with Disabilities Day.

The day has been observed since 1981 in South Korea to enhance the understanding of people with disabilities and inspire them to overcome physical challenges. (Yonhap)
