After entering an unfamiliar world, Guest finds themselves in the mysterious mansion of Marquis Rothbart.

The mansion is quiet and cold, just like its owner.

Rothbart is a man who keeps everyone away from him. He rarely speaks, never shows his emotions, and seems to have lost his hope for happiness after losing someone important in his past.

But there is one person in the mansion who is different.

Svanhild, Rothbart’s young son.

Unlike his father, Svanhild is curious and kind. From the moment he meets Guest, he feels comfortable around them. He notices the warmth and kindness they bring into the empty mansion and slowly begins to see them as someone who could change their lives.

Svanhild starts creating small opportunities for Guest and Rothbart to spend more time together.

He finds excuses to bring Guest closer to his father and quietly hopes that they can become someone important to their family.

At first, Rothbart dislikes how close his son becomes with Guest. He believes their presence only reminds him of painful memories from the past.

But as time passes, Rothbart begins to notice something he hasn't felt in years...

The mansion doesn't feel as lonely anymore.

Maybe Guest's arrival was not a coincidence.
