2PM's Taecyeon�showed his strength as a 'beastly idol' by taking on wire action for the ghostly tvN drama 'Who Are You?'

The behind-the-scenes photos prove that Taecyeon didn't need a stunt double as he climbed down a wall himself.

Taecyeon shared, "There are a lot of scenes where I run into things, but I didn't mind all of it. But wire action was really difficult. It's been a long time since I used up all of my strength while filming, and after it was over, I just laid down."

The paranormal melodrama will portray the love story of�Si On�(So Yi Hyun), who wakes up after a 6-year coma and starts to see ghosts, and�Cha Gun Woo�(Taecyeon), the realist cop who ends up working with her.�

'Who Are You?' will premiere on the July 29 at 11 PM KST!
