Since childhood, Lin Yao possessed a unique physical constitution; eating chili peppers when she was young allowed her hair to grow long so she could sell it to subsidize her family's finances. After turning twenty, her supernatural ability faded, yet she transformed into a super food-devouring king with an astonishing appetite that nearly emptied her mansion of food. Coinciding with the imperial court's political marriage alliance, all the officials scrambled to avoid it, so her father proactively recommended her to travel far to the Sheng State. Everyone thought it was a beauty trap, little knowing that the gluttonous princess had her heart set entirely on eating her way through the prince's estate, even planning to eat the Regent into poverty so she would be divorced and sent back home, hilariously kicking off a marriage alliance journey full of sharp contrasts.
