During my university days, I had a close friend who was a code enthusiast named ZY. We met on a coding forum.

A large part of my coding skills were learned through his guidance.

However, we had never met in person.

I remember we agreed that once I could build my own private chat window using code, I would treat him to a meal.

Later, I met Song Rui. Our topics shifted from code to me confiding my personal feelings.

I shared every moment of my life with Song Rui online, relying on the fact that we hadn't met in person.

From the initial sweetness to the eventual hurt I endured…

I had nowhere to say it, nowhere to vent, so I poured it all out to him.

I remember the first time Song Rui committed domestic violence against me, I sent the incident to ZY through code.

His coded reply was: "You can get a divorce. I will always be here waiting for you."

After breaking this barrier, I didn't message ZY for a long time.

Later, I got pregnant. I deliriously hoped my child could save my marriage but instead pushed my life into the abyss step by step.

The child was gone, and I developed severe mental health issues.

Later, my father also passed away.

In moments of brief clarity, all I wanted was to drag Song Rui, the culprit, down to hell.

At some point, a new family moved in next door. I often heard the couple arguing, mostly the woman cursing.

Later, I learned he was named Zhou Yan and worked at Song Rui's company.

I ran into the man from that family several times in the elevator.

Every time he seemed like he wanted to say something but stopped, and I always avoided him.

But his gaze was gentle, and he was very kind. He helped me take out my trash many times, as seen in the surveillance footage.

I unintentionally discovered through the surveillance footage that his wife was getting intimate with different men when he wasn't home.

One of those men was actually my ex-husband, Song Rui.

At that moment, I hatched a plan.

I got the employee phone numbers from someone at Song Rui's company.

Then, I anonymously sent the surveillance video to my neighbor Zhou Yan through coded messages.

I intended to use Zhou Yan to deal with Song Rui, but I didn't expect Zhou Yan to become a murderer.

And I was the mastermind behind it.

I was deeply trapped in the thought of myself being an indirect murderer, so much so that I didn't notice the police breaking in.

When my eyes focused on the policemen in front of me, the fear and extreme tension from the past few days relaxed, and when the handcuffs were placed on my wrists, I fainted.

In my last consciousness, it seemed that Zhou Yan said, "R, I am ZY."
