Archaeology student Lee Seol (played by Kim Tae Hee) was just an ordinary student yesterday, but she woke up overnight and she became the princess of the royal family of Korea! The frugal life is replaced by rich clothes and jade food; the knowledge in textbooks is replaced by various social etiquettes. This is not a dream, this is Li Xue\’s real life. The great changes that outsiders seem to be enviable, in Li Xue are all kinds of unsuitability. Among them, her home teacher Park Hae Young (Song Seung Hyun) is the one that bothers her the most. The only heir to the most powerful chaebol in the Republic of Korea, he is also a South Korean diplomat, and he looks handsome. With such a family teacher, Li Xue has undoubtedly become the jealous object of thousands of Korean women. But in Li Xue\’s eyes, Park Hae Young was just a demon sent by the sky to torture her. The relationship between the two is full of friction, but Li Xue and Haiying, who look at each other\’s dislikes, have become in love with each other for a long time. But the road to happiness has never been smooth sailing, but the prince will eventually hold the princess\’s hand and live happily ever after.
