After Returning to Beijing, My Aloof Sister Turned into a Sister-Controller!

Something has been wrong with my sister, who is known for her strict etiquette. When my mother advised me to give up dancing with knives and guns and instead learn piano, chess, calligraphy and painting, she came to persuade me late at night, "Sister, my sister likes your heroic appearance the most. You must not listen to mother's nonsense." When the lady in the boudoir secretly mocked me for being shameless in public, she attacked from both sides, "My sister can kill thousands of enemy generals and protect the world's peace. When will it be your turn to break her mouth?" When her fiancé regretted it and wanted to renew their relationship, she put her hands on her hips and cursed angrily, "My sister is kind-hearted and holds a high position. How can you be worthy of her?"
