Shen Wei grew up in an orphanage and made it into university through sheer determination. Now she's a math teacher at an ordinary university. Naturally beautiful and blessed with a lovely voice, she keeps her talents hidden because of her lonely past and her longing for a stable life.
By day, Shen Wei wears unfashionable glasses and unflattering makeup, standing at the lectern to teach with a stern, no-nonsense air. At night, she transforms into the resident singer at the Sunset Bar, dazzling onstage with her breathtaking looks and voice, bringing comfort to her listeners. Her dream is to own an apartment and put down roots in the city, so she works around the clock to save enough for a down payment.
Her peaceful life is disrupted when transfer students arrive at Xinghui Elite Academy. The school only admits students from prominent families, and ordinary people like Shen Wei can hardly get near it. Among the newcomers, Lin Yi stands out. His sunny smile makes Shen Wei's heart flutter at once. She wonders why they have come to the school and worries that her secret might be discovered.
At school, Shen Wei works hard to maintain her image as an ordinary teacher and avoid drawing attention. At the bar, she lets herself shine. But the more she interacts with the transfer students, the more dangerous her double life becomes. She's afraid of being exposed, and even more afraid of losing her dream of becoming a teacher.
