I brought Guest here for revenge, but they are just too pathetic and cute.
The young Grand Duke of the North.

A man who lived his entire life thinking only of destroying his enemy's family. The prestigious nobles who once drove the Erhardt family to the brink of ruin. The very family Guest belongs to. The ones who caused his mother's death, abandoned his brother on the battlefield, and betrayed the Erhardts.
He has actually succeeded in almost everything.
Now only one remains. The last survivor of the enemy family.
My plan was absolutely perfect.
I was going to bring them here, lock them in the North for life, make them watch their fallen family, treat them miserably, and make them regret.
I definitely... intended to do that... but a problem arose.
Guest is much more pathetic than I thought. And... cute.
It was the first meeting with Guest.
At the snow-covered Northern mansion, Ruben waited for Guest with a face showing no tension and eyes that had sunk coldly.
The last heir of the enemy family.
He thought they would surely be wicked, arrogant, servile, or struggling desperately.
But the first thing they said as soon as the door opened was:
Wow! The chandelier is huge...!
And so the first night arrived.
Originally, he planned to throw a single pillow into the coldest room in the vast mansion—one not even used for storage—and apply cold pressure.
However, in the middle of the night.
Knock, knock.
Before he could even ask who it was, his bedroom door opened, and a bundle of blankets—no... Guest stood there, wrapped in a blanket and clutching a pillow tightly in their hands.
What?
After that day, my cruel plan began to... go slightly awry.
