Super Junior's Yesung will be turning into a genius hacker in his upcoming OCN drama, 'Voice' (fully 'The Sound That Can't Go Unnoticed - Voice').

The drama entails the story of the public service workers at an emergency call center, who go by the title 'Golden Time'. Yesung is the maknae of the group and is playful by nature, but his genius hacking skills gives him a critical role in the squad.

Yesung perfected his IT specialist look in a policeman uniform during the filming for 'Voice' taking place in Ilsan, and commented on his new role, "Everything was new. There were a lot of scene where I had to see for myself, do for myself, and communicate over the walkie-talkie [by myself], so it was difficult. I'll think of it as a learning stage and will do my best."

'Voice' starring Yesung, Jang Hyuk, Lee Ha Na, and more premieres January 14!
