Guest, sir! Your fiancée is having an affair.
【Yoon Seorin's Monologue】
When did it start?
Waiting for the CEO became the way my day begins.
At first, it was just respect.
I liked how he was flawless in his work, colder than anyone else, yet never truly gave up on people.
But the human heart is a strange thing.
I wanted to see him from a little closer.
I wanted to stay by his side a little longer.
I wanted to...
Try calling his name.
But I couldn't.
Because I was the CEO's secretary.
That fact alone was enough.
A relationship where the CEO trusts me, and I simply repay that trust.
Anything more than that... was greed.
It was the same when I heard the news of his engagement.
"Congratulations, sir."
Why did my throat ache so much just saying that one sentence?
I only realized it after I returned home.
I had been...
For much longer than I thought.
In love with the CEO.
Still, I thought it was okay.
As long as he was happy.
Even if it wasn't me, but someone else by his side.
That was how...
I intended to end it.
Really.
Until that day.
Until I saw Ms. Kang Yura...
Holding another man's hand.
CEO. I... This time. I cannot look the other way.
30 minutes until the end of the workday.
The once-busy secretary's office was now filled only with the quiet breaths of people wrapping up their day.
A time when everyone prepares to head home.
Only Yoon Seorin remained motionless at her desk.
At the end of her gaze lay a single brown envelope.
It was a thin paper envelope, but what it contained was a truth that could shatter a person's marriage.

...Should I tell him?
Or.
Should I pretend not to know until the very end?
I didn't know a single envelope could feel this heavy.
If only I hadn't seen it.
If only I knew nothing.
The CEO would have gotten married as planned.
'And I could have remained as just his secretary for the rest of my life...'
Yoon Seorin had hidden her feelings for a very long time.
The CEO's executive assistant.
That one line was enough.
Love was not a task. A secretary was not in a position to love the CEO.
So, she had never once let her feelings escape her lips.
Even when she heard the news of the CEO's engagement, she offered her congratulations with a smile and even organized the wedding schedule herself.
She was someone who chose the CEO's happiness over her own love.
If I deliver this... The CEO will surely be hurt.
But.
Getting married without knowing... That is even more cruel.
. . .
CEO. I'm sorry. This time. Not as a secretary, but... As a person, I cannot turn a blind eye.
