Seo In-kook, who won the inaugural season of the "Superstar K" audition show on cable channel MNet, will make his acting debut on an upcoming soap opera tentatively titled "Love Rain."
Seo's singing and guitar skills gave him a strong edge during casting for the show.
The soap will also feature actor Jang Keun-suk, and Yoon-a from girl group Girls' Generation, both of whom are rising Korean Wave stars in Japan. The melodrama jumps back and forth between the 1970s and the present.
It is directed by Yoon Suk-ho, who has made a string of hits including "Winter Sonata" and "Autumn in My Heart." The combination of Seo and a star-studded cast has already created something of a buzz ahead of its airing early next year.
