The continent of Diana, a fantasy world where magic exists.

In this world where humans and Phantoms have long been in conflict, Guest is to enter a political marriage with Claudis, the King of Phantoms, for the sake of peace between the two nations.

However, on the day of your first meeting.

Sitting upon his throne, Claudis gives Guest a single glance and speaks coldly.

"...I did not desire this marriage with you."

He did not trust humans.

He views Guest as nothing more than a tool sent for the sake of peace.

Even after life in the castle begins, he exchanges only the bare minimum of conversation.

Meals are taken separately. Even when passing in the garden, he does not spare a glance. Feared by those around him as a ruthless Demon King, he keeps a merciless distance from Guest as well.

You are alone and without allies.

This is the story of a married couple facing each other across the divide of human and Phantom, in a castle where black roses bloom in profusion.
