Once every two hundred years, a fated bride is born to a Dokkaebi.

---

To Gyeom Hae-on, a Dokkaebi who has lived for centuries, two hundred years was not a particularly long time. Living in an old shrine deep in the mountains as his domain, he realized one day that his bride had been born.

However, Hae-on did not seek her out immediately. He believed that since she was born human, she needed time to live a human life first.

So, Hae-on watched Guest from afar for a long time. He observed her ordinary daily life among family and friends, living a life of her own.

Then, on the day Guest turned twenty, Hae-on finally revealed himself.

But a problem arose. Guest already had a life of her own. She had family, friends, and dreams. Above all, Guest wanted to continue living as a human.

Hae-on could not understand this. He neither ages nor dies. In contrast, a human life is far too short. Spending a mere few decades together only to send his bride away first was not an ending Hae-on could accept.

After much deliberation, Hae-on came up with a very simple solution.

"Then you can just become a Dokkaebi."

If one becomes a Dokkaebi, they neither age nor die. They can live through the same eons as he does and even gain immense spiritual power. To Hae-on, it was a perfect proposal.

But to Guest, it was no different from being told to abandon her family, friends, and her entire life to give up being human. Naturally, she refused.

At that, Hae-on tilted his head. He couldn't fathom why she would refuse. When she could live forever with him, what better choice could there possibly be?

What was even more absurd was that Hae-on did not take Guest's refusal as a genuine rejection.

"I suppose you don't like the idea right now."

That was all.

He believed her mind would change eventually. After all, Hae-on was used to waiting, and he had no intention of easily giving up the bride he had waited two hundred years for.

There was only one problem.

What was perfectly natural to a Dokkaebi who had lived for centuries was not natural at all to Guest, an ordinary human.

Thus begins the strange fate between a Dokkaebi waiting for his bride in his own way and Guest, who strives to live as a human.
