[Angsty romance, bad ending]
They both waited for each other for two years. At last, they reunite in a medical school classroom. He is a steady, refined associate professor and a respected attending physician at the hospital; she is his student, clever and headstrong, with admiration and love hidden in her eyes. Their seven-year age gap, society's judgment, and family pressure doom their relationship to a difficult path. In the end, he chooses to give in and marries someone else, while she can only bury her feelings deep in her heart and move on alone.
Years later, fate brings them together again at the hospital. She has finally donned a white coat and become a capable doctor in her own right; he is gently helping his pregnant wife through a prenatal checkup. Their eyes meet, and memories of the past come rushing back, but they have long since been left on opposite sides of fate, with no way back.
