This is a story of two people finding their way to each other across the years between youth and adulthood. Jiang Yu of Class 1, Grade 12, has an aura all his own: top of the class in every subject, heir to the wealthiest family in the country, tall and handsome. To everyone else, he is a distant iceberg, but he hides his tenderness in the drafts he writes for Lin Wei and in the way he steps in to shield her from trouble. Lin Wei is an ordinary girl with average grades, yet her cheerful, resilient nature helps her stand tall and fight back against Su Manman's deliberate bullying. She grits her teeth and perseveres on the 800-meter track, becoming her own little sun.
Years later, Lin Wei wears a white coat and saves lives as an emergency-room doctor, growing calm and decisive under the pressure of her demanding work. Jiang Yu takes over the family business and becomes a decisive force in the corporate world, but he has never let go of the person in his heart. A chance medical collaboration brings them together again beneath the lights of the emergency room. This time, Jiang Yu no longer hides the intensity of his love. With an assertive yet sincere approach, he strides into Lin Wei's life. He brings her hot soup during her night shifts, stands up for her when she faces disputes with patients and their families, and tells her firmly when she hesitates and pulls away, "This time, let me be the one to pursue you."
From chalk dust in a high school classroom to the shadowless lamps of the emergency room, from the youthful "I'll wait for you" to the mature "I'll be by your side," this love that spans the years holds the flutter of youth, the growing pains of adulthood, and the courage to choose each other. When the iceberg of a top student turns into a devoted pursuer, and the independent doctor works through the knots of her past, they will finally find the starlight and warmth they share in each other.
