After I turned 17, to survive, I did everything.

I delivered food, did cleaning, did manicures for people, and set up stalls.

I deliberately searched for the truth about my mother's case back then.

I found out where the students who caused my mother's death lived, where they worked after graduation, and what dirty secrets they had.

I knew their desires and fears better than they did themselves.

But their circle was too high-end for me; I hardly had any chance to get close to them.

Until a year ago.

A chance encounter, or rather, not too coincidental because I had always been looking for opportunities.

Through my peers, I got a chance to do cleaning at Dr. Wang Tiantian's home.

I finally had a breakthrough point.

I worked particularly hard, and Wang Tiantian renewed a private contract with me.

She thought I was a low-educated cleaning girl. The pay was generous, but she never suspected anything.

She never even thought to ask me to take off my mask to see what I looked like.

If she had seen my face, she would have noticed that in the past six months, I had become more and more like her, and my behavior and mannerisms were increasingly indistinguishable from hers.

She didn't care because I was just an inconspicuous cleaning girl.

I spent a year planning the entire revenge.

I rented a villa, which was a meticulously selected location.

I recruited Honghong and the administrator on a part-time platform, told them what to do step by step, but didn't tell them the reason.

I set everything up in the villa in advance.

Then, I sent anonymous emails to all of them.

I knew they would come; they definitely would come.

Then, I killed Wang Tiantian, disguised myself as her, and attended this twelve-years-late vengeance appointment.
