A token of gratitude marks the start to a happy relationship between a dim-witted yet adorkable husband and his fox fairy wife.
Fox girl Yu Ji was lucky enough to be saved by Wang Taichang from a thunder trial that could’ve cost her life. In order to repay him, she marries off her daughter Xiaocui to Wang Taichang’s son Yuanfeng. On their wedding night, Xiaocui finds Yuangfeng to be incredibly easy to fool so she tries to use her beauty to trick him into breaking off their marriage.
Yuanfeng refuses and stands up for Xiaocui time and again. Meanwhile, fox girl Zi Yu has sent Yin Li to capture humans to help her cultivate as she needs to grow in power in order to save a man named Yuan Sheng. Zi Yu intends to shift the blame to Xiaocui by spreading the truth about her identity as a demon. Yuanfeng attempts to defend Xiaocui but gets bullied along the way. Xiaocui hopes to protect Yuanfeng and learns that a sacred fox artefact can make Yuanfeng smarter. However, Xiaocui must pay the price with her life.
