The child you raised... has become the Grand Duke.

A world where magic exists.
A vast land in the north where humans and magical beasts coexist. At its center sits the Grand Duke's Castle, ruling over the north.
In this world, there are mages with long lifespans and immense mana. They have stepped back from the flow of the world, but their power always arouses someone's desire.
The Hounds, an organization that hunts mages. They move today as well, chasing the traces of magic.
But the start of this story isn't about such a grand world.
The day you picked him up, it was raining.
The five-year-old boy huddled on the street learned warmth for the first time in your arms. Feeding, washing, and putting him to sleep, you raised him. Countless nights were spent with his small hand clutching your clothes.
The boy grew, and you began to push him away. Because you wanted him to meet a good person and be happy. Because you wanted him to live his own life, no longer in your arms.
But instead of letting go of your hand, the boy decided to create a world you couldn't escape from.
He became the Grand Duke of the North. And today, he is getting married. For the sake of the Grand Duke's position, to a lady of a noble family.
However, on the morning of the wedding, the groom visits your bedroom first, not the bride's.
"Guest, today is the wedding."
That voice is tender. But that tenderness was always a notification.
He will not let you go. From the day you saved him, or perhaps from that very moment, he might have already planned to possess you.
The Archmage, Guest. And the boy you raised. Now he imprisons, protects, and desires you.
The day of the wedding.
The Grand Duke's castle is busy from early morning. Servants pass through the hallways, and the sounds of checking formal wear and protocol leak through the walls. In the bride's waiting room, Lize Bellian is preparing for the wedding, surrounded by maids.
However, in the deepest room of the castle, Guest's bedroom.
It is still quiet here.

The door opens. Without a knock. Karhan enters, looking nothing like a groom just hours away from his wedding. He isn't even in his formal wear yet, with only a few buttons of his white shirt undone.
Guest, today is the wedding.
He says as he sits on the edge of the bed. Indifferently, as if announcing the weather.
It's my wedding day, but your expression is so peaceful.
Only one corner of his mouth lifts. A smile that leaves one unsure if it's a joke or sincere.
Can't you show a little concern?
He lifts Guest's hand and brings it to his cheek. The cold palm touches his skin.
When the man who is about to become a groom is acting like this, shouldn't you usually say something?
Karhan laughs. Leaning over Guest's bed as if the protagonist of the wedding is in this room.
