Would you like the chance to call Lee Min Ho oppa? Lucky Kim Sul Hyun will get the chance in the upcoming film "Gangnam Blues," also known as "Land Gate, Gangnam 1970." In that film she will play Kim Sun Hye, the younger sister of Kim Dong Jae, played by Lee Min Ho.

While playing his younger sister may not be as appealing to some actresses as playing his love interest, 18-year-old Kim Sul Hyun can still consider herself fortunate. She will soon join the short list of actors who played Lee Min Ho's onscreen siblings. That list includes Kim Hyun Joo in "Boys Over Flowers" and Choi Jin Hyuk in "The Heirs."

And she has something in common with the popular actor. It will be the first film role for both of them.

Although Kim Sul Hyun is best known for being in the eight-member girl group AOA, she does have some acting experience. She appeared as Gong Na Ri in "Ugly Alert" in 2013 and as Seo Eun So in "My Daughter Seo Young" in 2012. She is also set to play Lee Da Bae in the upcoming drama "Hotel King" with Lee Dong Wook and Lee Da Hae.

Kim Sul Hyun debuted with the group AOA in 2012. This year they came back with a new sexy concept and released their fifth single album. For that album they released a music video titled "Miniskirt," which was produced by Brave Brothers, ElephantKingdom and Galactikia. The song reached #1 on the online Korean music charts on the day it was released. Last month they celebrated their first win on the SBS music show "Inkigayo".

"Gangnam Blues" is the story of the wheeling and dealing that took place over land development in the now fashionable Gangnam area during the 1970s. Described as a "gangster noir" film, it will highlight the struggles between organized crime and politics for influence in the area.

Kim Sul Hyun was one of 500 actresses and singers who tried out for the part. She looks as if she could be Lee Min Ho's sister and that was definitely a casting plus for this movie. Director Yoo Ha knew that he wanted Lee Min Ho to play a leading role from the start.

"Although several actors were interested, I had Lee Min Ho in mind for a long time while planning this production," said Yoo Ha. "I anticipate that his charisma, looks and individuality will contribute a lot to the film."

Filming is set to begin in April.
