[... please, protect this world.]

Uhh... sure..?

[Thank you, Tia-chan!! Farewell, young mortal~]

The obsidian-haired, amethyst-eyed boy across me drank all of the contents in his teacup and stood up. He flashed a pseudo-smile at me so I bowed in return.

"Well, I must be on my way now. You remember about the delegates that will visit the draconic kingdom Daemonorops, I asked His Majesty that I will be joining as well with the support of ojiisama, of course."

How could a ten year-old child be this eloquent? He is the main capture target and the Crown Prince of the largest human empire Coelacanth, but he should have more flaws too. I feel like I'm not talking to a child but to an adult instead.

"Do you mean that you'll be visiting the princess, Maxentius-sama?" I asked with a hint of curiosity.

"Yes, some bug is getting cocky and thinks that he could monopolize Sese-chan. Should I decapitate him?" He placed his hand on his chin as if pondering over something. "Torturing him in my personal abattoir must be better."

I shuddered at his thoughts.

This..! How could he think like that?! Seriously, if he lived in my previous world, he'll be treated like a psychopath!!

But... no one taught him about morality so it's the most natural that killing someone is normal. I just hope the Heroine who will soon come will be able to change his mindset.

We can't have our future Emperor go around killing people for fun.

"Y-Your Highness?" He snapped out of his thoughts. "Are you done with your... plans?"

"Yes, don't mind my earlier thoughts. It just slipped out so pay it no heed." He locked my eyes with his gaze that intimidated me. "Understood, Hestia Ceres Mantissa-ojou?"

"Of course I will, Maxentius-sama." I bowed.

He nodded in satisfaction and slowly disappeared from the room followed by his attendants. I just slumped back on the couch and breathed a sigh.

*hah

I thought I could never get out of that situation, thank goodness he was too immersed in thinking how to 'treat the bug with utmost hospitality'.

"How was it, imōto?" A slightly deep voice resonated in the room that I swiftly gazed to its direction.

A young man in his teens with lime blond hair that reaches his nape and eyelids and stern amber eyes, wearing a green and white knight uniform, leaned on the door frame with his arms crossed. His eyes may look cold but if you take a good look, there was a hint of worry in it. Overall, he was a handsome young man that is obviously sought out by noble ladies.

Harrison Chilon Mantissa, 15 years old. He is the heir to the dukedom and one of the hidden capture targets of 'Hey Milord, Lemme Capture Your Heart!!'. When the Heroine goes to the main stage of the game, which is Centifolia Academy, he is a first-year teacher in History at the age of 21.

In the original plot, he kinda hated his little sister who dared to torment an innocent and cute girl aka the Heroine. When they were children, they used to get along but when the Heroine came along, that bond shattered in a blink of an eye.

Hestia, the Villainess, further did her villainous acts towards her love rival when she stumbled on the information that even her beloved older brother takes the Heroine's side instead of hers. She would use her status to intimidate the Heroine and even push the latter down the stairs or to the lake.

In Harrison's route, he indicted his little sister himself with the permission of their parents. She got sent off to a monastery in the East, the fief of a Count who secretly rapes young nuns. She got molested and suffered in the streets due to her chastity being taken and could no longer serve the gods.

When the Heroine graduated at the age of 18, she got married to Harrison and became the Duchess Mantissa. They had two children, a boy named Heinrey and a girl named Diane, and lived happily ever after.

Let's get along with him, so as to save myself from a few death flags.

"Harrison-niisama..!" I stammered.

"Did he disrespect you in any way? Please tell me if he did..!" He ran towards me and held both of my shoulders. "Were you hurt because he wanted to break off your engagement?" I shook my head.

"No, I was actually relieved. Relieved that His Imperial Highness finally found someone to direct his obsession. Actually oniisama, I regret requesting it in the first place!" I grinned brightly that he widened his eyes.

"Are you sure? It was just yesterday that you asked to be the Crown Prince's fiancée, why are you acting like a different person?"

*gulp

Wha, I never knew he could be this sharp. As expected of the second-best capture target. Well, he is the heir to the Mantissa dukedom so being this sharp is just child's play.

"O-Oh come on oniisama, surely you jest..!" I awkwardly laughed. "I am your little sister Hestia, who else could I be?"

"But of course, forgive me imōto." He ruffled my hair.

"Tee~hee~" I giggled.

"But... do you want to find another fiancé instead? I heard the son of the draconic Prime Minister isn't engaged yet."

*cough cough

Is this really a coincidence or did that yandere Crown Prince tell oniisama? How could he!!

"But oniisama, I still wanna be with you. Do you really *sniff* want me to *sniff sniff* leave the dukedom *sniff* already..?" I asked, pretending to be hurt that he wore a panicked expression.

"Imōto, forgive this brother of yours..!"

Wha... even with an expression like that, he's still handsome! To think my brother is an ikemen, I'm so proud to be his sister!!

"It's okay Harrison-niisama," I shrugged. "It's not like early engagements are rare amongst nobility. I even have an acquaintance who has a husband already despite being in the same age as me."

"Yeah, I just hope you won't leave me that early~"

"Oniisama!!"

"Sorry, I was just happy to see you being what you were years ago... before the change... before the haughtiness..." He said with a wry smile while looking distant.

"Don't worry Harrison-niisama, I will remain childish to you and our parents only." I raised my fists against the air. "I just hope you won't find me weird like how my own maid looked at me."

"Certainly, you are my cute little sister after all."

Very reassuring oniisama but for some reason, there's still some doubt in the depths of my heart that you'd choose the Heroine's side instead of mine.

Harrison-niisama, please take care of me~
