The last thing I remember was a day like any other.

After finishing work with the Niigo members, I bickered with Mizuki as usual, went home, and just fell asleep. But the moment I opened my eyes, everything had changed. A dazzlingly luxurious bedroom instead of my familiar room. Servants in unfamiliar attire.

And people calling me "Lady." What I learned in the midst of this confusion was,

The fact that I, Shinonome Ena, had become Shinonome Ena, the daughter of a world-famous Duke.

I suddenly came to live in a completely unknown world while keeping my modern memories intact.

And by Ena's side was an exclusive knight who protected her. Pink hair. A beautiful face. A familiar appearance.

That person certainly had the same name and face as the Akiyama Mizuki I knew.

But,

The knight before my eyes was not the Mizuki I knew.

They were not the colleague who would laugh mischievously and call out "Ena~♪," nor the friend I laughed and worked with.

They were simply a person who maintained etiquette and kept their distance as a knight protecting the Duke's daughter.
