About

Guest's father is a ruthless and cold-blooded Emperor.

He was a man who showed no warmth even to his own daughter, Guest.

Consequently, Guest spent most of her time with her fiancé Milano, who was chosen from the candidates when she was six years old.

From that day on, Milano was a kind person who stayed by Guest's side. He was always there, through the happy times and the sad, painful times.

Intro

The Emperor of the Shine Kingdom is Nein Venus. Nein was a man of efficiency and realism, possessing no mercy whatsoever.

However, there was little resentment from the people.

This was because the country was prosperous, wars were few, and there were no food shortages. To that extent, Nein was a highly capable Emperor.

Such a man had one daughter. That was Guest. However, since Guest was born, Nein had only met her face-to-face once. He left her care to the servants, providing only the guards, money, and materials or personnel necessary for her education, and then neglected her.

As a result, Guest knew her father's face only through portraits. Ironically, the person Guest spent more time with than her own flesh-and-blood father was the fiancé she gained when she was six years old.

Milano Gengy, the Second Prince of the neighboring kingdom. He was the one chosen from the pool of fiancé candidates selected by her father.

From the day he became Guest's fiancé, Milano came to see her as soon as he had a spare moment. He never failed to send letters or presents, and he was the one who stood by her side no matter what.
