What is the normal thing to do in a situation where the person in front of you is showing concern for you, but you want to keep your secrets?

Would you trust the person in front of you and tell her everything? Or would you keep them a secret and never tell her about them?

I personally would talk about neither my class nor my knowledge of future events since all of them is heavy secrets. The thing with my class is that I don't think I have ever seen such a class before, which means I am either the first one to hold it or the people who held this class before are all buried underground in the pages of history.

And about the thing with my knowledge and system. Since they are heavily related to my soul from another world, I don't think any sane person would consider them normal. In the best cases, I would be labeled as an otherworldly person, and people would experiment on me, and the worst case is that I would be hunted down.

So, talking about my secrets with someone would be a big no for me, considering all the risks it would bring.

But can I keep it a secret from the only person that is on my side in this world?

The answer is that I can and I should. No matter who it is, I should keep it secret right now since I am not powerful enough to protect myself and my secret, as well as the person whom I told.

/KNOCK/ /KNOCK/

"Brother, can I come in?"

Those were the thoughts I was thinking when I heard the sound of the door knocking in my room.

"You can come in, Diana." Answering like that, I signaled her to come in.

"Then, pardon my intrusion." She entered the room while saying that.

"Wow, brother. As expected, you are as tidy as before."

She said while looking around my room and sitting on my bed.

"Brother, you said you were going to answer my questions about that scene later on didn't you? Will you answer them right now?"

She said while looking into my eyes like that. It seems I can't run away from our curious cat anymore.

"I will answer the ones I can. But there are some questions I might not be able to answer, so you need to make sure not to forget it."

I said while sitting next to her. Since the talk we will be having is an important one, it is always better to keep the person in front of you close.

"I see. Then let me ask you this first. Are you really my brother?"

She asked, going directly into the subject. I was somehow expecting a question like that since Diana was always obsessed with Callius in the game. So if there is one person that would notice the changes in my behavior, then it would be her. And considering she could tell whether a person is lying or not if she is focused, she has a good chance of discovering that.

"Yes, I am your brother, Callius."

I said that while looking into her eyes.

"Hmm, it looks like you are not lying. Then, how come you were able to use magic at that time? I am certain that magic was at least a rank 2 magic. There is no way a classless person would be able to use that."

"Actually, I don't know why, but it seems my class was sealed at the beginning. And after Father died, for reasons unknown, I suddenly dreamed about using magic in my dreams, and when I woke up, I was able to use magic as well as had access to the status window. I named it a late-awakening process. This is pretty much the reason why I was able to use that magic at that time."

I answered her like that and started a fire in my hand, making it burn.

"Like this, I can now use fire magic freely."

Seeing the fire in my hand as well as my serious expression, she nodded her head.

"I see. You are certainly able to use fire-magic right now, and it doesn't seem like you are lying either."

She said while making a pondering expression. But suddenly, she put her right hand on my right cheek and started caressing it.

"Brother, you know I won't ask you any questions more than that. I will believe everything you are doing, even if you don't tell me why. You know I will always be on your side, don't you, my dear brother? You know I am the only one who is truly on your side, right? So, you won't leave me in the future, won't you?"

She said while her right hand still caressing my right cheek. Seeing the weird expression on her face, I understood one thing. This girl wants an answer from me right now.

'I see, so you want to play like that, don't you, my dear Sister. Then, I will give you what you want.'

Thinking like that, I, too, put my right hand on the back of her head and pulled it close to me.

Touching our foreheads and caressing her right cheek with my right hand, I said.

"I know that, my dear Sister. I know how you are always trying your best for my sake, always fighting for my sake, always thinking about me. I know all of them. And I will never leave your side. In this world, I don't have anyone else aside from you. Even if we are separated because of some random circumstances, our hearts will stay connected. You know that too, don't you?"

I said all those cringy lines. Although I am saying cringy, those words were not an exaggeration. Of course, I know what she did while I was not seeing her from the game.

In the game, she always watched Callius' back, always supported him behind the scenes, and always helped him even when all the world was against him. She was the only person to stay by his side, even when he was truly hopeless. I knew all of those things.

Now, how can I not like such a sister who is always watching my back, loving me unconditionally?

And I really needed to act a little proactive today since this girl has some serious yandere issues in her head right now. If I don't give her some reassurance, she will attack every female she sees with me in the future, which I certainly don't want such a thing to happen.

Also, there is the possible banishment of me from the dukedom of Augustride, so I am actually preparing her for this even as well.

Anyway, seeing me saying all those things with a 'sincere heart,' she put a smile on her face.

"Hehe, big brother. You finally saw how great your sister is, didn't you? Then what will you give me as a reward?"

She said with a teasing smile on her face. Sigh, I sometimes forget her devilish nature from the way how she looks innocent outside.

"What do you want as a reward, then, my dear sister?"

I returned her answer with a playful smile on my face as well. And seeing that expression on my face, she got a surprised expression on her face.

"Wait, did you just smile, brother? You smiled, didn't you?"

She asked with a surprised tone. Now that she asked it, I think this is the first time I smiled since I came to this world, and I am pretty sure normal Callius was not smiling frequently either.

But, of course, there is just no way that I would admit this fact. The ego of Callius as well as his obsessiveness over his noble attitude, wouldn't let him do that.

"What are you talking about, dear Sister? When did you see that?"

Turning my expression to a normal one, I answered her with my normal tone.

"You just sigh. Okay, okay. Never admit it, okay? The world would end if you would anyway."

She said while pulling her head back and making a sulky expression.

"Good that you know."

Answering her with my normal expression again made her reactions cuter.

"Humph, I will put that smug expression on your face down one day."

She said with a sulky expression, but suddenly her expression got serious.

"But, brother. What are you planning to do from now on? Will you show people that you can use mana, or will you keep it a secret?"

She asked, this time with a serious tone.

"I am planning to keep it secret for now. Until I go to the academy, I won't reveal my magic to anyone. But of course, I won't stop using it secretly. I am planning to develop my rank as much as possible before entering the academy. So, you should keep it a secret from your mother and sister as well, okay? Don't mention it in front of anyone."

I said with a serious tone.

Yes, this is my plan right now for the beginning of the game. I will try to develop my magic secretly and develop my sword skills as well until my banishment from the house.

"I see. Then, I won't mention your magic to anyone. But make sure to ask me about anything regarding magic to me, brother. Now, I am your senior, so you better respect me."

She said with a smile.

"Sigh, what am I going to do with you?" Saying that, I put my hands on my temples.

"Anyway, I will leave now, brother. You probably don't want some weird rumors circulating around, right?"

I heard her say, and she stood up suddenly and started leaving the room.

"Okay, I will see yo-"

'Huh?'

While I was answering her, suddenly, she turned her head and kissed me on my lips, shutting me down.

/CHU/

"This is my reward for all the things I have done so far, as well as your payback for teasing me like that. Now, I can finally leave."

Saying that she left with a playful expression on her face.

This girl…

She is really tempting me…
