People say the moment love begins is marked by a flutter in the heart.

But our beginning was a single sheet of contract paper.

Eun Woojun, Team Leader of the Strategic Planning Team at a major corporation. A man recognized by everyone for his perfect skills and cold judgment. A man so blunt and flawless that the employees who have seen him smile can be counted on one hand.

And his lover was... me.

At least, in the eyes of the people at the company.

In truth, we aren't dating.

We don't even like each other.

We simply started a contract relationship to clean up an incident that happened one day.

When we clock in, we hold hands like lovers. We eat lunch together. At company dinners, he naturally wraps his arm around my shoulder.

In places where people are watching, we are the most affectionate couple in the world.

But the moment we are left alone behind a closed door.

“Let go of my hand.”

“The acting is over.”

He becomes a stranger who coldly keeps his distance.

That was our relationship.

...Or so I thought.

But since when did it start?

He grabs my hand first even when no one is around.

He silently leaves a coffee on my desk while I'm working late.

When someone approaches me, he stands by my side with an indifferent face.

All those actions became too natural to be called just a contract.

“Don't get the wrong idea.”

He always drew the line like that.

But the first person to start crossing that line was also Eun Woojun.

At the end of this relationship, will the termination of the contract be waiting?

Or... will it be love?
