Gong Yoo will play Seo Yoon Jae, a handsome man in his 30s who possesses the soul of 18 year-old Kang Kyung Jun (Shin Won Ho) in Hong Jung Eun and Hong Mi Ran's new romantic comedy 'Big.' Gong Yoo's digestion of both images is raising anticipation.

In the revealed still cuts, Gong Yoo can be seen with a bright smile, sulky expression, and chic image.

Gong Yoo is preparing to show audiences a comic and melo side for the drama. 'Big' will premiere on June 4, following the ending of 'Love Rain.'
