The Republic of San Magnolia.

In a realm where even the faintest shadows whisper untold tales, I came to realize that the forgotten often hold the most powerful narratives.As an avid admirer of the world's most beloved series, I never imagined that one night's rest would pull me into its very fabric.“Why on earth am I stuck in this world? And why, of all people, am I him?”I had become Arthur Nightingale—Class A’s most unremarkable student. A magic swordsman barely worthy of mention, ranked 8th among the first-years. A mere footnote in the grand story.Still, with this body’s abilities and my own insider knowledge, I figured I could carve out a peaceful life. Or so I believed.“This was the only way,” the voice repeated, resolute. “The only way to stop her.”Little did I know how truly unique Arthur Nightingale was—or the path this journey would force me to take...

Three years after entering the palace, Yongning Palace’s Yan Shu meiren, has still never met the Emperor.

The palace full of concubines tried to win his favour, only she, immersed in a melon eating system, has no time to spare for him.

How would she know that one day, she actually ate a shockingly big melon——

Yan Shu, “!!! No wonder he never enters the harem!”

Wait…

There seems to be something wrong somewhere… then what did she enter the palace for?!!

The new Emperor, Yu Wen Lan, has two secrets.

Since his ascension to the throne, he has gradually lost his male functions; yet at the same time, he can read minds.

Getting used to seeing their false words and hypocritical faces every day, he grew all the more unfeeling.

That was, until one day, he heard a special heart’s voice——

Yu Wen Lan paused, narrowing his eyes to look in the direction of a delicately pretty and pure looking girl.

Until she ascended to the position of Empress, Yan Shu also didn’t know how she had jumped unreasonably on the Emperor’s bottom line repeatedly, yet had jumped straight in, becoming the first person to be in his heart.

Perhaps, it was just her good luck.
