In 2012, Lee Min Ho and Kim Go Eun coincidentally met at Kim Hee Chul's party. They enjoyed chatting with each other so much, they decided to go somewhere else for supper. They enjoyed it even better that they made a promise to meet once a month for a meal together. The time was always the same: before dawn. They became best friends that could really share their thoughts to each other. They knew they were fond of each other, but that's it. Just friends, no drama. Right? Until they really get a drama together: TKEM. Will they stay as only friends, or will they be more than that?
