Ethan Clarke’s younger brother starts to date early in school, and the homeroom teacher asks for a parent-teacher meeting. Since their mother is away on a business trip, Ethan steps in to meet the teacher in her place. To his surprise, the teacher turns out to be Olivia Parker, Ethan’s first love. Seven years ago, after Ethan harshly broke up with Olivia, she waited in the snow all night outside his building, hoping for reconciliation, but he never went down to see her. Now, years later, they meet again. Olivia still holds feelings for Ethan, while Ethan has buried his feelings for her because of a warning from Lily Anderson.
