Actress Shin Se Kyung fell in love with Girls' Generation (SNSD).

Today, Shin Se Kyung posted on her Twitter, "Ah... I can't fall asleep because it's so good." When people asked what she was referring to, she replied "Girls' Generation... Can't you hear my heart beat."

Again, she posted, "What do I do? My symptoms are serious. What am I doing not sleeping. The world became a beautiful place all of a sudden. I'm going to close my eyes and try to sleep now. The stage video will probably play over and over in my head..."

Shin Se Kyung was actively advertising Girls' Generation new album I Got a Boy released yesterday, revealing her friendship with them.

Internet users who saw this commented, "You're so cute," "I'm in love too," "SNSD is worth falling in love with."
