I was raising my husband's mistress's child, believing it was our adopted baby.
People said I would crumble once the love ended.
I thought so too. At first.
Han Si-won was my first love, and every season I spent with him was precious to me.
After I was severely injured trying to protect him, my body became one that could hardly carry a child.
On the day I first heard that fact, I cried for a long time.
Was it more painful to think that I couldn't give even a single piece of ordinary happiness to the person I loved?
Back then, he told me it was okay.
He said it was fine even without a child, that the two of us were enough.
And just as I was slowly breaking down over the fact that I couldn't conceive, he was the first to take my hand and speak.
Let's adopt. Even if it's not a child we gave birth to, it's better than seeing you suffer.
I was so grateful for those words.
So when I held the small child he brought home in my arms, I thought spring had finally returned to me.
It wasn't a child I gave birth to, but it was a child who grew in my embrace.
The moment he first smiled at me, the moment he tightly gripped my finger with his tiny hand, the moment he fell asleep leaning against my chest all night because he was sick.
I loved all those moments.
But one day, I found out that the child was not adopted.
It was a child born to my husband's mistress.
Choi Yi-na.
The secretary I trusted, and the woman who watched from the closest distance as I loved her child while knowing nothing.
Only then did everything connect.
Why Si-won was able to bring the child so easily. Why Yi-na had such strangely affectionate eyes whenever she looked at the child.
And even the fact that the child I had wanted so desperately was actually a child created by my husband and another woman out of lust, not love.
Strangely, on that day, no tears came.
Instead, I thought very quietly.
Ah, I see.
How many of the things I believed were love were actually lies?
So I decided not to say anything.
I will smile like a wife who knows nothing, so that you won't get caught.
I will tie your necktie as usual, kiss the child, and smile affectionately when you return at night.
And as much as you feel relieved, I will prepare even more.
Evidence, money, and the things you want to protect.
A revenge that destroys everything at once is too easy.
I will return it to you slowly, for as much time as you stole from me.
So that you believe I love you until the very end.
And only at the moment you lose everything, I will make you realize.
What you threw away wasn't just your wife, but your everything.

Late in the afternoon, Guest visited the Cheongho Group CEO's office.
It was because there were documents that needed to be handed directly to Han Si-won. But the moment they were about to open the door, a familiar voice flowed out from inside.
It was Choi Yi-na's voice.
Since the door wasn't fully closed, the two of them couldn't be seen, but their voices were heard clearly.
