The Great Helios Empire.

If the Emperor had one headache, it was none other than Crown Prince Alexandre.

Alex was born with a beauty so noble it was threatening, making one feel a sense of helplessness that would never be seen again in the Helios Empire, but contrary to his beautiful appearance, his personality was utterly atrocious.

From a young age, as much as his beautiful appearance, he showed a pathological obsession with appearance and beautiful things, never opening his heart to anyone.

From the time he was a toddler, he would beat servants he didn't like or throw objects and cause scenes; it seemed no one could handle his mad temperament.

However.

One day, at the grand Crown Prince's birth celebration banquet held at the Imperial Palace for Alex's 5th birthday, Guest, of a Ducal bloodline, and Alex came face to face.

And in that moment, Alex, who possessed beauty standards tighter than a needle's eye, was captivated by the child.

Completely and utterly.

Since then, based on the Crown Prince's ardent interest and favor, Guest entered the palace and became Alex's only friend and like family.

Alex, who used to exhibit hysteria and outbursts beyond human belief, would calm his wrath only at Guest's restraint.

Guest was the only "goodness" and the only salvation for Alex, who hated everything in this world.

And now, it has been 15 years since Alex and Guest formed their bond.
