Superstar K winner Seo In Guk has signed on for a role in a new romantic comedy/horror drama. The drama titled "The Master's Sun" stars So Ji Sub, who recently appeared in "Phantom," and Gong Hyo Jin, who starred in "Pasta" and "The Greatest Love."

In the drama, Seo in Guk will play Kang Woo, a former soldier who is the head of the security division at a shopping mall.

So Ji Sub plays the greedy CEO Joo Joong Won who hires Kang Woo. Gong Hyo Jin plays Tae Kong Il, the secretary with the supernatural ability to see ghosts. The drama is written by the Hong sisters, who created "You're Beautiful" and "My Girlfriend is a Gumiho," and will be directed by Jin Hyuk of "Shining Inheritance" and "City Hunter."

"I'm honored to be acting with So Ji Sub and Gong Hyo Jin," said Seo In Guk. "I will work hard at this great opportunity and help the drama shine."

The role will offer the singer a chance to portray a very rough, masculine character.

"Seo in Guk has both a gentle and a masculine side. The latter is a good fit with the character of Kang Woo," said a representative from the drama production company. "You can look forward to seeing a new side to him."

The singer-turned-actor began his career by winning the talent reality show "Superstar K" in 2009. He came from a poor family and always dreamed of becoming a singer. And while he released a few successful songs, none have been quite as popular as expected. Some netizens think he is a better actor than a singer, unlike other idols-turned-actors. One fan wrote that he shines more when he's acting. Another said that acting offers him a better chance to display his charm.

His unexpected acting career began when he played the dual roles of Kim Chang Mo and Kim Jeon Seol in "Love Rain." His first leading role was in the drama "Reply 1997."

This year is turning out to be a good one for Seo In Guk's career. He snagged roles in two films, "Police Family" and "No Breathing."

He also recently released a single "With Laugher or with Tears." Actress Go Hye Sun appeared in the music video for that song and composed "Were We Happy?" another song that he released. He then debuted in Japan with the release of the single "Fly Away."

And now he has a role in this drama, which will air in June.
