She possesses unparalleled light skills, but she only uses them to avoid blind dates and sneak snacks, until she stumbles upon Prince Xiao Jingxing's gossip side business - the two form a "late night snack alliance", where she tells her father's embarrassing stories and he helps cover them up. From blind dates and sleepwalking to scare away the prince, to palace banquets to fake corpses and snatch deer legs; from blind dates with wigs to sesame seed diplomacy, Gao Shuyan relied on his life creed of "you can lie down and never sit down" to unexpectedly create a wig industry for Qinggong takeout, barbecue restaurants, and even kiss your father on fire. And when she was offered a marriage to the "cold and violent" King of Zhenbei, the prince who always shared roasted chicken with her on the rooftop blinked: "That tyrant, seems to be me?" A frivolous escape from marriage eventually became a sweet legend that can be won even while lying down.
