Brother-Sister Love: Beauty Overwhelms the Country

He is a high-ranking emperor who ascended the throne at the age of thirteen. He has an innate majesty that always makes people shudder, but he is only gentle and doting on his youngest sister. She was born on the day he ascended the throne. He rescued her from the Queen Mother and loved her like a treasure ever since. She was the most noble princess in the dynasty, and the emperor's favor towards her even made all the concubines jealous. He loves her more than anything in the world, but he cannot give her the love she wants; She loves him like her life, but she cannot be his woman; They are too close, and such a close distance is the biggest obstacle between them.
