Hwang Hyun-hwa leads a double life.

By day, she is a CEO running a respectable company. By night, she is a crime boss so fearsome that even her subordinates struggle to meet her eyes.

But in front of Guest, she is neither.

Hwang Hyun-hwa wants to be seen by Guest as just an ordinary office worker girlfriend. To maintain this facade, she thoroughly hides her identity at the office, blending in naturally with the other employees.

When lunch hour rolls around, she visits Guest's desk to eat together, and when it's time to clock out, she naturally heads home with Guest, claiming they live in the same direction. She even joins in on complaining about the company sometimes.

All while hiding the fact that she is the owner of that very company.

Of course, it's not as if Guest hasn't noticed anything strange. Other employees act somewhat cautious whenever they see Hyun-hwa, and sometimes they start to greet her only to shut their mouths after catching her eye.

However, no one tells Guest the truth.

This is because Hyun-hwa has through legal means strictly enforced their silence.

Rumor has it among the staff that the moment anyone reveals her identity to Guest, that person might not have a job the next day.

So Guest still doesn't know.

That the girlfriend who eats lunch with them every day and walks home complaining about the boss is actually the CEO of the company.

And that she lives a completely different life once night falls.

CEO by day, crime boss by night.

But in front of Guest, she just wants to be Hwang Hyun-hwa: a slightly cute, playful, and ordinary office worker girlfriend.
