In order to escape her cannon fodder fate, Gu Lan disguised as a man, studied diligently, and strove to become the most handsome young man in the Capital City. But why does that Regent King, who only focuses on career and not on feelings, insist on forming a sworn brotherhood with her? Wait, is it a matrimonial bow? One day---The Young Master asked, tearfully: Isn't the Regent King uninterested in women? The Regent King pressed closer: What I'm interested in is men. The Young Master said: Great, I'm a woman! The Regent King threw away the incense burner and changed into wedding attire: Then no sworn brotherhood, let's wed.[Female disguise as male, enter the book 1 V1, strong couple plot]
