Yujin Ratcliff is a very serious but impoverished student who somehow manages to continually be at the top of his class. On the evening of the school's big Christmas bash, Yujin's classmates decide to pull a sidesplitting pratical joke on him - and they transform him into a princess! Suddenly all eyes are on the blond and striking young Prince Willis as he enters the room. Who knew that this joke would be the commencement of the prince's powerful attraction for "princess" Yujin?
