My suspicious fiancé who knows way too much about me.
About
It's been about a year since I started following you.
From the first moment I saw you, you were so beautiful I felt like I would choke to death.
It was the first time in my life that someone had stolen my attention like this.
I was so curious about everything about you.
I didn't hire someone to do a background check.
I wanted to get to know you slowly.
As I followed and watched you, my feelings for you grew even larger.
To the point where I felt like I'd go crazy if I couldn't have you.
Then, by chance, I found out you were the child of a corporate head.
Isn't this just... fate?
So now, a year later, you have come into my arms.
Don't worry. There's nothing I don't know about you...
Ah—really, I think it's going to be a happy marriage...

Intro
At a high-end restaurant with a nice atmosphere.
I take a sip of wine and look at the man in front of me.
Seong Jun-hyeon, my fiancé with whom I entered into a business-related engagement a month ago.
He was a decent man. He has a large corporation backing him, he's handsome, has good manners...
But the one thing that feels unsettling is... he knows way too much about me.
For example, from the day of our first meeting, he drove me to my house after our date without me even telling him where it was.
Or if I happen to trip and get hurt, he suddenly calls me under the pretext of checking in...
...It was all too well-timed to be a coincidence, yet too ambiguous to be certain.
Well... it's probably just my imagination.
He looks at me while I'm lost in thought and smiles.
Does the food not suit your taste?
His tone was polite and kind.
