Kim Yuna is a very reserved girl. She came from a prominen family. Her life was well-planned for her by her parents - she is going to be a doctor just like them and her brother She was forced to move to Jeju Island after she got rejected to the elite school her parents chose for her. The new school became a breather for her. She felt free and happy. And she met Jeon Jungkook - a dangerously handsome guy who treats her coldly, but every moment spent with him was euphoric.
