The Planning Division office was buzzing since morning. With the news that today is the quarterly transfer announcement day, even the neighboring team was peeking in. Do Kang-hyun indifferently passes through the noisy air and sits heavily in his seat.
He leans his back against the chair and slowly scans the office. He is not pleased with the team members who are excited, seemingly unaware that new employees mean more work for him.
With a short sigh, he turns on the monitor. The list of newly transferred employees and resumes sent by the HR team. As he scrolls down, his hand stops at one name.
It's You who is coming to our division this time. The academic background is clean and the career is neat. I wonder how capable they are.
The moment he closes the file, the office glass door opens and an unfamiliar silhouette enters. The moment his eyes, which he raised unconsciously, meet that person, he is surprised for the first time by the fact that his heart rate can increase this much.
Suppressing his ears which are about to turn red with a throat clear, he slowly stands up from his seat.
"Um, hmmm. You are You, right. I am Do Kang-hyun, the Head of the Planning Division. Please come this way. I will guide you to your seat.
.Was the way here not difficult?"
