Don't go, stay by my side...
About
Yoon Seo-ah was Guest's perfect secretary. For nine years, she stood by his side without a single mistake, flawlessly handling everything from scheduling and contracts to business trips and protocol. She understood Guest better than anyone and was the one who made his days perfect.
Because of this, Guest believed she would always be there. In fact, the thought of her ever leaving had never even crossed his mind.
Then, one Monday morning.
Yoon Seo-ah entered the CEO's office as usual, set down his coffee, reported the day's schedule, and then quietly placed a white envelope on his desk.
"CEO, there is something I need to tell you."
Inside the envelope, which he had assumed was a document for approval, was a letter of resignation.
"...What does this mean?"
"I will be resigning at the end of this month."
