Onii-sama stared curiously at me while waiting for my answer.
I gulped at his eyes while my mind quickly summarised the things I was about to say.
I was going to spit out the truth and make it clear I wasn't his real sister to remove any guilt he will have in the future.
It made me sad that the original Onii-sama probably mulled over it depressingly when Roselyn was bullying the one he loved.
It made my heart ache even more when the one in the game felt terribly sad and guilty when Roselyn died, but Ivy's presence repaired that hole in his heart.
Roselyn didn't think much of her brother as anything much, but Andrew Villinie still held dearly onto the fact that they came from the same parents and that he'd watch this sister of his from birth.
I didn't think of him as a game character with a role anymore, but as a human being.
Which was why I was going to make it so he doesn't feel guilty and become depressed.
What if Ivy doesn't respond to his feelings, who will save him from the abyss of sorrow?
Ivy obviously went for the big fish here, and it would pain me to see Onii-sama's sad face as he chooses between his 'sister' and the one he cherishes.
I didn't care about what happened to Ivy, but Onii-sama didn't deserve to suffer like this.
If he knew that I was just a parasite that invaded his sister's body, then he wouldn't have so much conscience and the later guilt on this matter.
I indulged in his kindness and indulged in the pleasure of being loved, but that much was enough for me to remember for a lifetime.
Perhaps it was because nobody cared for me like this in my last life that I cherished Onii-sama so much, so I decided to repay the favour by making his guilt lighter.
And it felt nice to finally have the chance to tell him the truth.
I've always felt that our relationship was unable to breath because I was always hiding this fact from him, a guilt of my own.
I was in the role of his 'sister', but I didn't deserve any of his sibling affection as someone who only intruded into her body.
"Onii-sama..." 'So I still call him by that name, something I got from my former world...', "The truth is, I'm not your sister."
He forced a smile but was obviously confused at this.
"You're...not my sister? What do you mean by that? Roselyn, you're not an illegitimate child. I saw you grow in Mother's belly myself."
"No, it's not that. You see, I come from another world...think of it as a complete different dimension...and I actually don't belong here. I just took hold of this body, that's all."
I was expecting either a revolted glare or more confusion on his face, but instead he just stared thoughtfully at me.
"......."
I dared not to speak under this gaze, but I could feel cold sweat on my forehead as the silence became almost overbearing.
"Roselyn, you're still my sister, aren't you? Even if you've possessed this body....you've still been with me since you were born, right?"
I was stunned by his conjecture and that he was so confident that I didn't over take this body anytime when it was still a child to a teenager.
But this was Onii-sama; he had watched me over since I was a baby.
He would definitely notice if there was something wrong with me, whether it's by change of my habits or personality itself.
I was so happy I could float straight up to heaven, because he had accepted me as his sister.
It was an outcome that I dared not to hope for, because the disappointment would be too much to handle.
So it's better to think of the worst outcomes and be prepared for it.
Onii-sama didn't look like he was lying, but he opened his mouth to speak.
"Actually, I think that what you just said proves my theory."
Theory? What theory could Onii-sama have related
Before I could ask, Onii-sama continued.
"I actually have a secret of my own, if you'd like to listen."
I nodded quickly because he decided to listen to my secret, so I'll gladly take in his like he did with mine.
Onii-sama looked strangely composed and understanding even after this shocking secret of mine, which I passed off as strange.
Did he already know I wasn't from this world?
Did that mean he was also from that other place, like me?
Perhaps he was also stuffed into the role of Andrew Villinie, just like I was with Roselyn Villinie?
But his personality and likes fit every single one of the descriptions in the game, not even a professional could act that well unless you were the person themselves.
I had a lot of years to observe him, and nothing was off mark and he did not show any signs or habits that was common in the modern world.
"If I told you I used a time-reversing spell, would you believe me?"
I answered immediately, "Yes, I would."
There was nothing to not believe here, Onii-sama would never lie to me.
"Ivy....you do know her, right?"
I nodded quickly.
"In the other timeline, I was quite foolish and regrettably fell in love with her. The same thing happened to His Highness and a few other students."
He then let out a sigh full of regret.
"At that time, she was too innocent for the world. But after she....became queen, she fell corrupt too under the influences of riches and her father."
The period of time Onii-sama was talking about must have been after the otome game ended, because every route ended with a marriage scene to the specific male lead you chose.
In this case, it seemed like she chose Albert.
But under the influences of her father? Wasn't her father a very doting person?
Don't tell me he used Ivy?
Then wouldn't him getting promoted to the title of Count be bad?
"His Highness changed too, and then the managing of the country fell on me. Obviously I had to accept the offer, but I could tell that the nobles were getting too corrupted."
And so were the Royal couple.
I could tell he wanted to say that, but decided to keep his mouth shut when it came to that part.
"The country was suffering while the nobles were enjoying their parties and pleasuring themselves, and I simply couldn't watch any longer."
"To this day, I still regret not doing anything but watching as His Highness and Queen Ivy fall into the abyss of love, not caring about the world or anything else. It was sickening, if I had to be honest."
Onii-sama never used such crude words to describe a situation, no matter how bad it was.
Someone started calling for Onii-sama, and he turned his head at me before he left.
"You'll always be my sister no matter what. However, this time's Ivy.....she acts a lot like my other younger sister."
The warning shocked me, but I quickly gathered myself up.
"Elijah." My tone rang out clearly. "Surely, you must know something, don't you?"
