Ji Yan, a poor girl, won a full scholarship to Holy Infant College with her excellent grades. However, she accidentally broke the sky-high price antiques belonging to the public relations department of "Stardust" and was forced to disguise herself as a man and join the debt repayment. In the luxurious and dangerous "Stardust", while disguising her identity to learn public relations skills and cope with academic and work pressure, she interacted with the indifferent department head Gu Yanchen, the enthusiastic Su Muyang and others. As the relationship with Gu Yanchen grows, the risk of identity exposure is getting closer and closer. Ji Yan needs to find a balance between lies, debts and emotions, uncover the secrets of "Stardust", and finally break free from the gilded cage and embrace his true self and love.
