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.
