Min Yoongi and Bae Sumi are high school sweethearts. They fell in love 2 years before graduation, as they started their senior years of high school. They were a stereotypical, cheesy, couple without a care in the world. Then, high school ends. Bae Sumi is writing her first novel. She needs to be in Korea. Min Yoongi has been given the opportunity to study overseas to become the rapper he wants to be. The thought of living apart is unbearable to both of them.
