Seo In Guk spoke up about acting in drama 'Love Rain' on the October 22nd installment of 'Naver Line Star Chatting,' revealing that, "Singer turned actors are scared when they first act." This edition of Naver Line Star Chatting hosted the stars of 'No Breathing' including Girls' Generation's Yuri and Lee Jong Suk.

He said, "The first script I received of 'Love Rain' was all in the Seoul dialect.  All I could show Director Yoon Suk Ho was the secret regional dialect I used for twenty years.  I showed him and he turned out to really like it."  He also revealed that for his 'Love Rain' character Kim Chang Mo, he gained weight, changed his hairstyle, and wore glasses. He said, "I was 22 pounds heavier than I am now."
