Talk about wonderful kdrama chemistry. The new tvN drama "Who Are You?" will pair 2PM's Ok Taecyeon with actress So E Hyun.

Singer-actor Taecyeon, who recently appeared in the global edition of "We Got Married" and starred in "Dream High"will co-star with So E Hyun, who recently played Seo Yoon Joo, the deceptive wife in "Cheomdamdung Alice."

While they may ask the question, "Who Are You?" of each other, it will primarily be directed at the ghosts they encounter. In yet another kdrama take on the supernatural, "Who Are You" will focus on the newly departed and the clues these ghosts leave behind.

Taecyeon, 24, plays Geon Woo, a detective who only believes evidence he can see, and So E. Hyun, 28, will play Si On, a woman who can see apparitions. Together, the two detectives will help the spirits of those who have departed using the items they have left behind. The character Si On has not always been able to see ghosts. She was in a car accident and spent six years in a coma. As a result, she lost her memory but acquired the ability to see spirits. She wants to honor their requests but since Geon Woo is her boss, she cannot act on such requests unless she convinces him they are real.

Not only will Si On convince Geon Woo that she really can see ghosts but the two will draw closer through the shared experience. If this spooky love story sounds familiar, it's not says producer Lee Min Jin.

"The romance between this woman who sees spirits and a man who doesn't properly value the human spirit will be very different from anything you have seen," said Lee Min Jun. "It's going to be a new genre with plenty of heartwarming moments when the leads try to aid the spirits."

The role will be Ok Taecyeon′s first in two years since his appearance in "Dream High.

Before "Cheomdamdung Alice," So E Hyun appeared in more than a dozen dramas, including "Happy Ending," "Glowing She" and "Heartstrings." She also has a cameo role as a lawyer in the current drama "I Can Hear Your Voice."

According to Key East, So E Hyun's agency, she is passionate about her new role. In their statement, they said, "She is evaluating her part and carefully preparing for the role, especially since it is a new genre, a ghost melodrama."

The drama will be aired in July on tvN after "DatingAgency: Cyrano."
