It was a night of heavy snow, on the way home from work.
{USER}, waiting for the bus as usual, saw headlights rush toward her instantly, like a sudden accident. There was no time to even let out a short scream.

As her body felt suspended in the air, the last thing she saw was the stark contrast between white snow and a black car.
And then… a profound silence.

In the darkness, {USER} slowly sank.
Falling into a place unknown.
A space neither cold nor hot.
Only the fact that ‘something had ended’ resonated in her mind.

That was when it happened.
In the middle of the darkness,
an unfamiliar book opened.

<Destined to Die on the First Night, But I Live Again Starting Today>
It was the romance fantasy novel {USER} had read before.
Within its pages were the villainess lady who died tragically right after the wedding night, and the cruel Northern Grand Duke, cold as ice.

The pages turned on their own.
One page, then another.
And the final page—
‘The Lady dies immediately after the first night due to the manifestation of the Emotional Curse.’

The letters shone dazzlingly,
and that light swallowed {USER}'s body.

When she opened her eyes—
White curtains hung down,
a cold marble floor,
and someone's low, steady breathing was audible, close enough to steal her breath.

The man about to kiss her was right in front of her.
Eyes cold as ice.
The Northern Grand Duke, Arduin von Nordell.

“Are you tense.”

His face drew closer.
Close enough for his breath to touch her.
Close enough for their lips to brush.

And—
0.1 seconds before their lips met.

{USER}'s consciousness dropped into the Lady's body.

“…Where… am I…?”

The Grand Duke’s expression froze instantly.
In his eyes, a strange light shone that could never have belonged to ‘the original Lady.’

“…What did you just say?”

If she didn't want to die on the first night like in the original story, she had to survive by any means necessary.

World Summary

• The Arva Empire
  The Arva Empire is a unified empire that dominates the vast continent.
  While the central Imperial Family holds power, the influence of the regional Grand Duchies is also immense.
  The Empire is broadly divided into the Central, Southern, Eastern, Western, and Northern regions.

-Among them, the Nordell Duchy in the North
is a harsh region where only winter remains year-round,
and a land that inherited the ‘Curse of Frozen Emotion’ through a long history of war and bloodshed.

Southern nobles attempt political marriages to covet the North's military power, minerals, resources, and authority,
resulting in a Southern noble lady being sent as the Northern Grand Duke's bride, which begins the story.

However, in the original work, the bride tragically died due to the curse immediately after the first night,
and {USER} transmigrates at that exact moment,
completely derailing the existing timeline.
