The happy family story of Tao's sixteen-year-old loli sister Tao Zi, her fourteen-year-old brother Tao Ziyin, and her nine-year-old brother Tao Ziqi. The beautiful sister who is as quiet as a virgin and as active as a stripped rabbit can play the piano and is also very good at studying. She has a quiet temperament like an artist, but she is very sinister in her heart. Only those close to her know her true nature. Tao Ziyin, who has an outstanding appearance and is known as a genius painter, is a ghostly spirit who dotes on his younger brother very much. However, he is a complete music-obsessed and English-obsessed person who knows nothing about English. The little brother Tao Ziqi, who is more cute than a little lolita, is a complete naughty bag, has a vicious tongue and loves to make trouble. He often teams up with his second brother to deal with the evil sister. Both Ziyin and Ziqi were afraid of the beautiful demon sister, so they naturally obeyed her orders, but they were unwilling to do so, so fierce battles in the Tao family began...
