During the day, she is Chi Xia, a low-key top student in the School of Economics, holding a scholarship and working hard for graduation; at night, she transforms into Lily, the top star in the club, and walks among the rich, just to repay her mother's sky-high medical expenses. When Xu Jiaming, the heir to a wealthy family, breaks into her two lives at the same time, the encounter that started with a lie gradually gets out of control - he sees through her disguise, but gives an unexpected answer. "It doesn't have to be perfect, it just needs to be true." When debts, rumors, and shadows of the past come one after another, Chi Xia must make a choice: continue to live under a mask, or take a gamble and find her own way between moonlight and sunlight?
