When I 'Died', My Husband Regretted Cheating on Me

The group chat of Lab Team A buzzed with playful teasing about the team leader, Brian, and Sarah.

[Brian, you and Sarah should be more discreet. We all saw what happened in the lab today.]

[Exactly! Who moves a bed into the lab like that?]

At that moment, Brian casually brought me a plate of freshly cut fruit and affectionately patted my head. Yet, all I felt was an icy chill, as if summer had turned to winter.

He didn’t know that I was an undercover supervisor sent to his team by our higher-ups. I monitored every experiment he conducted, directly issuing commands through the team’s group chat.

Unfortunately, I was also aware of every passionate encounter between him and Sarah.

Later, I messaged the chief supervisor.

[In three days, I’ll personally infiltrate the experiment to identify who’s been placing toxic substances in the lab. After that, I’m done with this mission.]

——

[We understand. Don't worry. We will support you.] They replied.

Just then, Brian’s phone rang. The warm, doting look he’d been giving me while I ate the fruit vanished instantly. After listening to just a few words, he hurriedly grabbed his coat to leave.

"Alli, something came up at the lab. I need to go."

Before I could say a word, he was already out the door.

At that moment, messages popped up in the lab group chat from Sarah.

[Brian, hurry up! I’ve got a new bed ready.]

[I can’t wait any longer. You’ve got ten minutes.]

[I’ll be there in five.] He replied.

Another group member chimed in with a teasing comment.

[Brian takes five minutes to drive, but in the lab, it’s always an hour-long ride, haha!]

I stared at the screen, my chest tightening with pain.

Sarah was a graduate student who joined Brian’s lab after finishing her studies. During one experiment, she accidentally inhaled a significant amount of a gas with hypnotic properties and lost control of herself. She pulled Brian into a reckless act right there in the lab.

Instead of resisting, Brian, captivated by her alluring figure, responded with even more desire.

From that point onward, their relationship spiraled out of control. Traces of their intimacy could be found in every corner of the lab.

Five minutes later, with trembling hands, I opened the lab’s surveillance footage.

Sarah was wearing a translucent chiffon shirt, her pale skin visible through the sheer fabric. On the lab table, she had laid out a pile of contraceptives.

"Brian, do you think these are enough?"

Brian had his back to the camera, so I couldn’t see his expression. But his movements were deliberate. With a swift motion, he tore off the only garment Sarah was wearing.

"Not today. You’re taking it all in this time," he said.

Under the dim lab lights, their entangled figures were uncomfortably clear.

I clenched my fists and continued watching the surveillance footage, tears silently streaming down my face until they blurred the screen.

The magnified view showed Brian’s face as he gazed at Sarah, his eyes filled with an almost consuming intensity.

"Brian, with all this passion, how can your wife handle you?" Sarah teased.

Hearing her words, he punished her harshly. "Don’t mention my wife. I could never bear to treat her this way."

When I saw Sarah spit a liquid into one of the experimental containers, I couldn’t take it anymore. I shut off the monitor and rushed to the bathroom to vomit.

Looking at my disheveled reflection in the mirror, I suddenly felt an overwhelming urge to sleep, right there and then.

After composing myself, I checked my phone again. Brian was leaving.

"My wife’s waiting for me at home. Let’s wrap it up here today," he said.

Sarah pouted, reluctant to see him go. "Brian, can’t you stay with me a little longer? I need you the most right now."
