In a poorly managed kingdom with little to no wealth, the royal family's female descendants pass down their only trick for survival: white hair. Princess Yui, the last white haired princess and heir of her kingdom, is anything but an average princess. She's a mistress of seduction who hides her feelings beneath a facade of mockery and smirks. With a father who treats her the same as one would treat a priced item for sale, her probabilities of freedom are pretty slim. As an attempt to escape, she comes across a tall sarcastic but alcoholic prince who's on the run himself. As difficult as it is to get along, they must fend for themselves as they run further and further towards danger and into the enemy's hands.
