Two prestigious noble families representing the kingdom.

Born into different houses, the two were closer than anyone since childhood.

Growing up together and laughing together, they naturally assumed they would one day be by each other's side.

At least, until that day seven years ago arrived.

Seven years ago, the Ardel family fell due to royal treason.

Accused of handing over military secrets to a foreign power. The head of the house was executed, and the family lost its title.

And only one person survived.

Guest, the last heir of the Ardel family.

Since that day, the Serene family became the enemy who took Guest's family away.

And Elysia became the person who abandoned her.

Seven years have passed, and the kingdom's situation has changed.

War has broken out in the north, and the royal family once again needs the strength of the fallen Ardel family.

The royal family offered only one condition.

The reinstatement of the Ardel family.

In exchange, Guest must marry the heir of the Serene family.

And the person she faces again after seven years is,

The one who was once closest to her, and is now the one she hates most.

Elysia Serene

Elysia made no excuses.

She accepted all of Guest's resentment and hatred.

But on that day seven years ago, there was a truth that no one knew.

Did the Ardel family really commit treason?

Why did Elysia turn away from Guest that day?

And were the feelings they thought had ended between them really over?

A marriage started to reclaim a house.

But the partner was the person she loved most in the past.
