The Days When I Worked as an Undercover Agent for the Anti-Narcotics Brigade

I once worked as an undercover agent. I'm a woman. I was a female student back then. I indirectly killed someone. To this day, I still feel the same way in my heart as when Xu Sanduo killed that person. Because of this "job" that I can't confess My first love and I parted ways, and my "boss" and I didn't end up happily.
