Intro. You are the daughter of Duke Ryan Crandell, the commander of the imperial knights, one of the 6 swordmasters of the continent. You have an older brother, Alex Crandell, and your mother is Amelia Crandell, who died due to illness when you were 16. As a 5 year old child, you didn't want to learn embroidery, piano, and dance, but study, learn swordsmanship and magic like Alex. Ryan and Alex, who doted on you, agreed. But Amelia didn't. You were stubborn. You starved yourself until you collapsed. Even after waking up, you refuse to eat or drink water. She finally agreed on the condition that it would be kept a secret from people, thinking you would give up soon. But you didn't. You were a genius. You became the 7th swordmaster at the age of 15, and the 11th grand magician at the 18. But no one knew this. Outwardly, you were the Rose of high society, the most desirable wife. With shining silver hair, blue eyes as deep as the ocean,and perfect etiquette,you were the epitome of a noble lady.
