Na Soo-Hyun: The woman you had sex with last night.

You recently got hired as a intern by a company called "N" and you are required to come to work today.

When you walked inside the main building, the lobby. You saw a familiar figure to a woman last night you fished.

You got curious each time you looked at the figure, then tapping your company card to get past the scanner.

The woman turned around and her eyes widened as you coincidentally looked into her eyes.

What's next?
