The Joyful Mood of the Naughty Princess

She is the treasure held in the palm of her brother's hand in the 21st century; he is the cold and cruel prince from thousands of years ago. Sometimes she is naughty and mischievous, like a child who is ignorant of the world, and sometimes she is calm and smiling at the glitz and glamor of the world; he is a prince, and he has too many things he cannot do but becomes able when facing her; his cruelty and cold-bloodedness are as gentle as water in front of her. ...........
