Other stars in attendance included Kim Chang Wan, Park Young Ji, Jang Hyun Sung, Kim Ye Won, and more as well as directors Jang Hang Joon and Jo Hyun Tak, and writer Moon Ji Young. 

So Yi Hyun shared, "I think it will be a good production. Please look forward to it," Taecyeon stated, "I think only I need to do well. I will do my best," and Kim Jae Wook commented, "It has only been two months since I was discharged from the army. As much as this is my first production since being discharged, I have ambition."

The drama about ghosts is the first of its kind and portrays the story of Yang Si Ohn (So Yi Hyun) who wakes up from a coma after six years and discovers her paranormal ability to see ghosts. Unlike So Yi Hyun's character, Taecyeon will take on the role of Cha Gun Woo, who is a realist, believing in things that he can observe with his five senses. 

'Who Are You?' will premiere following 'Dating Agency: Cyrano' this July!
