I met my husband, Baek Cheong-un, back in college, seemingly by pure chance.

One day, when it was raining particularly hard, I went to class without an umbrella. Even after the lecture ended, the rain showed no signs of stopping, so I stood at the building entrance, waiting for it to let up.

That's when Cheong-un appeared before me.

Saying he had accidentally brought two umbrellas that day, he saw me without one and handed it over without hesitation.

That was our first meeting.

The next day, I stopped by a cafe, wondering how to return the umbrella, and ran into him again by chance.

Strangely enough, we kept running into each other after that. In the hallways, in classrooms, at cafes. It was as if we had made a promise to meet.

As these accidental encounters repeated, we grew interested in each other, and that interest naturally turned into affection.

We started dating and got married not long after.

Cheong-un was a husband who only cared about me.

He knew better than anyone what I liked and disliked, and he loved me so much that he couldn't seem to spend a single day properly without me.

Perhaps it was because of that intense love.

Things I had thought were a bit strange before started happening much more frequently lately.

It felt like Cheong-un knew things I hadn't even told him.

He knew about things I experienced before we even started dating,

"Honey, you said you'd been here before when you went to Busan with your friends, right?"

"Huh? Did I tell you that?"

He knew about my physical condition when I hadn't mentioned it, or he knew exactly where I had been.

"What did the doctor say? Is your headache okay, honey?"

"Huh? How did you know?"

"You told me you were in pain in your sleep last night. You said you should go to the hospital as soon as you woke up."

At first, I just thought I must have mentioned it offhandedly.

But it didn't stop at just one or two instances.

And that suspicion turned into action today.

Late in the evening, Cheong-un came home from work and said casually,

"Honey, we're out of toothpaste. You should've bought some when you went to the market earlier."

In that moment, I stared blankly at his face.

I had never told him I went to the market today.

In the end, I couldn't contain my curiosity.

Could he have hidden a recorder somewhere? Is he tracking my location?

That night, after confirming Cheong-un was fast asleep, I carefully picked up his phone.

The password was my birthday.

I unlocked it easily and checked one by one for suspicious apps, messages, or photos.

Then, suddenly, an unfamiliar KakaoTalk conversation caught my eye.

[Boss, 5:23 PM. The Madam has headed out. It seems she is going to the market in front of the house.]

My fingertips froze instantly.

That was the exact time I had actually gone out to the market.

I stared at the screen, holding my breath.

Just as I moved my finger to read more of the conversation,

I heard a low, sleep-heavy voice right beside me.

"Honey. I told you to go to sleep. What are you doing with my phone?"
