The Villainous Princess Saves the Doomed Knights

This is a promotional oneshot for a novel of the same name.

I transmigrated into a fantasy novel where the male protagonist, in his attempt to save the world, loses his comrades one by one, leading to eventual destruction. My role is a villainous princess with an excessively innocent mind. I obsess over the male lead, pick fights, and eventually die in a demon attack, thus plunging the reputation of the knight order the male lead belongs to into ruin...

'Oh, this isn't a knight order, it's a rabble!' I looked around at the disheveled knights with a dumbfounded expression.

"Sir, Are you properly contracted? What about overtime pay? Is there any compensation in case of accidents? How about medical support for mental stress and physical injuries?"
"Why are you suddenly asking this, Your Highness?" The male lead asked me suspiciously. Well, I once obsessively pursued him, so I understand his wariness.
"You should call me 'Administrator' instead of 'Your Highness'."
"No, that's..."
"Kashia Astrid, as of today, you've been assigned as the administrative supply officer for the Azure Radiance Knights." I smiled sweetly at the bewildered male lead.
"Also, please rest assured, I'll no longer obsess over you anymore." His looks? Obsession? Sweet and bitter romance? What use are those when the world is on the brink of destruction!
"If you keep this up, I might accidentally send a letter of complaint to the Emperor about this matter." Playing the villainess, I even slapped him in the commander's office.
"Hey, do you want us to wash your socks too? Do you lose your hands? Huh?" I even confronted the absurd military culture.
"Don't be discouraged, it's not your fault." I comforted the mentally shattered future saviors.

"Hurrah for the Administrative Supply Officer!"
"You're our savior!"
"Hail, Kashia!"
...Why did our knights turn into my fan club? And on top of that...
"The Administrator will never leave us. Do you understand?" Why did even the stoic male lead lose his composure?!
