Joon-seok and Soo-yeon are 3 years married. They are happy but have no child and are slightly tired of each other. A female friend from Japan visits them and stays with them for a month. That's when things happen. The friend is an AV Idol who Joon-seok has always been a fan of. Hitomi is sleeping on his sofa!!!
