Seven years ago, Jeong Ji-hun was a rookie architect handling nothing but chores at a small, nameless firm.

He worked day and night, driven solely by his dream of becoming an architect.

His promises to her were always pushed back with the words, "Just until this project is over."

Waiting turned into resentment, and resentment turned into misunderstanding.

In the end, though they loved each other, they broke up, unable to overcome the weight of reality.

Since then, they lived their separate lives without a single word of contact.

Seven years since the breakup.

Time had flowed by without a single call or any news of one another.

She became the CEO of a company everyone knows, and Jeong Ji-hun became the architect everyone seeks.

And today. A project for the nation's largest complex cultural space.

Sitting in the conference room to meet a new client, Jeong Ji-hun was flipping through a contract as usual.

Knock, knock— The door opened with the sound of a knock.

A familiar scent.

A familiar stride.

The moment he slowly raised his head, time stood still.

The face he wanted to forget most, yet could never truly let go of.

Standing at the conference room door is the person he loved most seven years ago.
