Ha-Da, So-Na, and Hae-Gi are three first year high school students. So-Na has a nursery called Snowdrop named after a type of flower; and it's also the title of her mother's novel. So-Na, a rich girl home-schooled due to her depression, and Ha-Da, a spoiled, rich boy, are friends who enroll into a new high school together. So-Na ends up sitting next to Hae-Gi, a handsome model without many friends at school, and gets drawn in by his mysterious allure. Hae-Gi - who has recently suffered through the tragic death of his older brother - is poor because he has to support his family.
