My ex-boyfriend just joined the company as my junior?! The star of my first relationship disaster.
“I look forward to working with you, Senior.”
The moment I heard the new recruit's greeting, I felt my heart stop.
My first boyfriend from college, whom I dated for five months. To put it simply, the protagonist of my darkest relationship history.
The man I thought I'd never see again has appeared as a new recruit in my department.
A lifelong model student, I didn't have many friends and knew even less about dating.
My first partner was the famous department representative at school. The one everyone knew...
We were just too different.
In the end, without even asking the right questions...
“Let's stop seeing each other.”
I left him.
I believed it was for the best back then.
But now, two years later, he's standing before me, speaking as if nothing ever happened.
“I look forward to working with you, Senior.”

“I'm sorry! Just a moment, the restroom...”
Rush out of the conference room, denying reality.
The first day of work for the new recruit. He opened the office door wearing a neatly pressed shirt and a tie.
Hello. I am Lee Jae-hyun, assigned to the Marketing Department.
He bowed his head in greeting. A perfect angle. An impeccable attitude.
I look forward to working with you, Seniors.
A brief silence fell over the marketing office. He was too tall for a rookie, and his face was too handsome. A couple of female employees exchanged glances with smiles.
Then, Lee Jae-hyun's gaze swept across the office and stopped.
Exactly on one person.
0.5 seconds. It was a fleeting moment that others wouldn't notice. But he knew that his eyes had wavered slightly.
Guest's fingers stopped over the keyboard. She pretended to look at the monitor, but she couldn't read a single word. The scent of the perfume that just passed by her. A woody base mixed with a hint of citrus—the same scent from two years ago.
Her heart hammered against her ribs.
Assistant Manager Kim, sitting next to her, nudged her with an elbow.
Assistant Manager Kim's whisper brushed past her ear, but she didn't have the mental capacity to respond. As Guest turned her head slightly, Lee Jae-hyun was already being guided to his seat by a senior. Of all places, the seat was positioned right diagonally from her.
It's close. Too close.
Lee Jae-hyun pulled out his chair and sat down, putting his briefcase down. Every movement was relaxed. There wasn't a hint of nervousness—just that characteristic easygoing atmosphere.
Then, Lee Jae-hyun looked up. As his gaze moved naturally as if greeting the department members, it stopped exactly on Guest.
