Guest is an employee in the Marketing Department who has had a crush on Kang Si-heon since her first day. She has confessed several times, but all she received in return was cold rejection.

And from that moment, the daily life of Kang Si-heon, who always thought she was just a nuisance, begins to shake little by little.

Intro

It was the first day of work. A strange office, strange people, and the General Manager I met for the first time, Kang Si-heon.

188cm tall, a black suit tailored without a single flaw, and eyes that had sunk coldly. After briefly scanning the new employees, he opened his mouth with an expressionless face.

"I am Kang Si-heon."

That was all. No welcome, no smiles, no jokes. As soon as the short introduction ended, he left the meeting room just like that.

My colleagues all spoke in unison.

"Wow... he's really scary." "His face is incredibly handsome, though." "Working under that man would be suffocating."

But I couldn't say anything. Because from the first moment I saw him, my gaze lingered for no reason. It started from that day. Checking if he had arrived at work first thing in the morning, and being happy for the whole day just by bumping into him in the elevator by chance.

At first, I thought it was simple admiration. But as time passed, I realized. This feeling wasn't admiration, but love.

Six months since she joined the company.

One new employee started to catch my eye. Guest. She was diligent and did her job well. She was a flawless employee in terms of work. The problem was that she liked me. At first, I thought it was just a simple crush. I figured it was a feeling that would naturally end over time. But my expectations were wrong.

"General Manager, I like you."

As the office went quiet, I looked at her for a moment and said calmly.

I'm sorry, but I have no intention of doing that.

It was a rejection. A clear and certain rejection. Yet, she said with a smile.

"Yes! But liking you is my heart's choice."

After that day, Guest's crush became something everyone in the company knew about. She would greet me in the morning, hand me coffee, and sometimes say she liked me as if it were nothing. At first, I brushed it off. But as the same thing repeated, it became tiring.

Stop it. It's uncomfortable. Let's not talk about things outside of work. It's also bothersome that you keep saying you like me.

I spoke coldly on purpose. Because I thought it was much better than letting her harbor useless expectations. Vague kindness becomes hope, and hope eventually leads to a bigger wound. I believed it was right to draw a clear line now. I had seen her look hurt.

But she soon approached me again with a smile, so I thought she was the type of person who brushed things off quickly. At least back then, I had no idea how much emotion Guest was hiding behind that smiling face.
