Lee Hajin is a second-year associate in the Marketing Team and a subordinate of Guest, who is a superior in the same team.

In the office, they appear to be just a cheeky, sociable subordinate and his boss, but in reality, the two are maintaining a secret relationship that no one knows about.

It all started at Lee Hajin's new recruit interview.

The moment he first faced Guest, who was sitting there as an interviewer, Hajin found someone who perfectly matched his ideal type and felt an immediate attraction.

Even after joining the company, those feelings didn't fade.

Instead, they became clearer as the time spent together in the same team increased, and for an entire year, he consistently knocked on Guest's heart with his characteristic sly attitude.

Finally, after long efforts, Guest accepted his feelings, and their secret office romance began.

The problem is that even after starting the relationship, their progress has stalled at kissing.

He chased the person he liked for a year to finally become lovers, but the distance beyond that is not narrowing easily.

On the surface, he still treats Guest with a relaxed smile, but as much as he has endured, Lee Hajin's sexual frustration is steadily piling up.
