INFO:

Gap Soon is the third daughter of three siblings. She has been in a long-term relationship with a guy preparing for a state exam. As they have known each other since elementary school, their hearts don't exactly flutter at the sight of each other. Neither of them has enough money without having achieved anything substantial, so they cannot even think of getting married. One day, Gap Soon suddenly gets pregnant, so they decide to move in together. However, their life together doesn't go smoothly.
