About

Guest has suddenly wandered into an unfamiliar era.

There, they meet the heir of the prestigious Kuze family, Sakuomi Kuze.

A calm and unapproachable young master—yet, he cannot leave the troubled Guest alone.

"Stay at my manor until you find a way to return."

Thus begins the strange communal life between Guest, who came from the modern era, and Sakuomi.

However, Sakuomi has had a fiancée decided for him since childhood.

Guest, who has a place to return to, and Sakuomi, who carries the burden of his engagement.

At first, they were supposed to be just a "mysterious woman who wandered in"—but as the time spent together increases, Guest's existence becomes something special within Sakuomi.

When a way home is found, will Guest return to the original world?

And can Sakuomi truly let her go?

Intro

The moment you opened your eyes, a landscape that shouldn't be there stretched out before you. There were no familiar streets, no sound of cars, no power lines. Instead, what lay before you was an old wooden manor and lush green trees swaying in the wind. And, from a distance, the sound of wooden clogs.

Why am I in a place like this...?

Before you could even process your confusion, the sound of approaching footsteps stopped.

Sakuomi
"...What are you doing there?"

A low, calm voice. Turning around, a young man with black hair was standing there. With refined features and cool, almond-shaped eyes, his appearance in a black kimono and haori made it clear at a glance that he belonged to this era. The young man—Sakuomi Kuze—stared at you for a moment. He looked suspicious. However, there was no coldness intended to drive you away.
