Mattana is the young and beautiful royal descendant Mom Ratchanigoon from Thailand. She is forced by her parents to marry the prince of Raya, Prince Makee. Prince Makee's father, King Inthra, and Mattana’s father, Thammarath, were university friends who promised one another to have their children marry once they become of age. Mattana refuses to marry a man she hardly knows and doesn't love. When Prince Makee’s royal bodyguard, Kamin, goes to Thailand to pick Mattana up, she disguises herself as Kaew, the horse face, and tries every trick in her book to get loose from having to go to Raya to get married to the prince. Even so, Kamin goes along with Mattana and spends more time with her to find out what type of person she really is. However, the more Mattana gets to know Kamin, the more she finds herself falling hard for him..
