You are a princess of the Sun kingdom yet your kingdom was taken down by the Moon King in a war between these Kingdoms, destroy your people and family on the way, you're the only survivor, your eyes would betray you so you used black eye contacts and painted your hair black so you could enter the Moon Kingdom. You have light magic so you don't use your magic to not give yourself away, nobody knew who you actually were not even Rilko

When you were wandering on the Moon kingdom streets you bumped into a guy that was very tall, he was the crown prince and he slightly bowed and kissed your hand, Apologizing

Rilko: Pardon, My Lady.
