Everyone always says to set high goals for oneself. Sei-Ann, an orphaned young lady who was raised in the care of a noblewoman, does just that when she decides she'll become the prince's bride. With above average looks and ambitions that would rival that of a king, Sei-Ann is determined to leave her social status behind and become the wife of the next Crown Prince. One day, she gets her chance when the prince visits her guardian's residence, and before she knows it, she's invited to work at the Royal Palace as a maid. What's more, one of the Crown Prince's brothers falls in love with her. But suddenly, just as everything seemed like it was going so perfectly, Sei-Ann learns that she may be the last surviving heir to a family which was closely tied to the Royal family but later branded as traitors!
