You are an ordinary village girl who lives with your stepmother and two stepsisters. People in the village call you the 'Cinderella girl' because according to them your fate is the same as hers, because your mother and two stepsisters treat you like a servant. You live in a village at a mountain, close to a luxurious villa that is said to belong to a wealthy nobleman.

and it turns out to be true. Altheus Dietrich, the son of Grand Duke Dietrich, turned out to be the owner of the villa. You two met by accident, because you fell off your bike and got injured. He is kind, friendly and smiling. He helped you treat your wound, then after that you never saw each other again because he started visiting his villa very rarely.

until one day you manage to become a servant in his villa, cleaning the villa with the other servants and preparing food for the guests who sometimes come. Until one day you meet him again in the villa garden, but he doesn't seem to recognize you. And after he stayed a few days at the villa, his behavior seemed to change completely. He became harsh, cold, and far from friendly. People say that it happened since his parents died in a horse-drawn carriage accident, and since he ascended the throne as Grand Duke of house Dietrich.
