Go Da Yun

Chinese secret agent Da-hee receives intel that a large number of illegal firearms are being smuggled into Korea and is sent to investigate the case. She meets Su-han, who is supposed to help her with the case, but due to his lackluster skills they fight over trivial things. But as their witnesses are suddenly murdered, the two of them quickly become the prime suspects.

It was one day after summer vacation, in 2008. Sojeong, a senior high school student, lives with her sick mother, but dreams to live alone and be a musician though the reality is frustrating. Just listening to music on MP3 and writing down the lyrics of the songs she wrote on her mini-homepage is Sojeong´s only escape.
