Ji-Min and Chul first started dating 10 years ago. They now live together as loves. People now often ask them "When are you going to marry?" or "Don't you want to get married?" Whenever they hear these questions, they ask back "Why do people get married?" They are happy just being together. Sometime, Ji-Min and Chul imagine their life with a child, but they believe it's just idle thoughts Ji-Min works to make a documentary and Chul works as a part-time instructor. To them, idle thoughts are not in their near term future. That is until the red 2 lines appear on a pregnancy test.
