The naïve low-level discipline of Zongtian residence, Zhan Yunchang, has been suffering from her unrequited love for Lang Guichi, her eminent senior brother for six full years before she finally acts on her impulse driven by alcohol and bared her heart to him. However, she gradually discovers that Lang Guichi’s gentle demeanour is in fact harbouring aloofness which resulted from his unbearable past. Before long, Zhan Yunchang makes acquaintance with another senior brother, Cang Yan, who is free-spirited and uninhibited by nature. Nevertheless, he seems to be hiding his mysterious past as well.
