This " The Butterfly Diary of the Sonorous Rose " was about the thrilling encounter of a female anti-drug agent codenamed Butterfly who had infiltrated the underground organization. She became a valiant policewoman after graduating from the police academy. Her beauty was as charming as water, but she had no choice but to endure the rain and wind. After the rain and rainbow, she was neither angry nor discouraged and became a sonorous rose. When she participated in a special operation by chance, the boss of the underground organization of the Multinational Group took a fancy to her because of her outstanding appearance. The commander-in-chief of the military region who followed and investigated this special case urgently sealed her police file and compiled a special service file with a criminal record. She was allowed to infiltrate the underground organization as a high-class club hostess.
