The Prohibited Isekai Life of a Certain Transmigrating Brother and Sister

"Look, wake up. You're gonna be late if you don't wake up soon, okay?

A comforting voice I'm used to hearing. When I woke up to it, my beloved stood by the bed and peered into my face.

"... good morning. Chizuru."

"Morning!... As always, you're just not sleeping well"

"I was doing some research late last night, so I was extra sleepy..."

When he returned it, Chizuru said, "Yes, it is," and sat down on the bed.

Chizuru is my one-sided opponent, as well as my twin sister. We've been together ever since we were born, and it was natural to be next door.

And if you noticed, I was in love with her. My one-sided thoughts are not a temporary distraction, they have been going on since I was a child to the present day.

The first time I realized this feeling, I said, "I'm crazy. It's unusual." I worried about it.

I couldn't stand what was bothering me by myself and have consulted on anonymous bulletin boards online. However...... the answer was still what I had imagined. "If I lived with you all the time, I wouldn't normally like you" or "If I'd lived apart before, and I didn't know you were my sister and brother, I know," or "I'm pathetic, but maybe I shouldn't tell you how I feel," they all told me to keep my mouth shut and cut off my feelings for my sister.

Seeing the public reaction, I tried many times to give up on Chizuru. But the more I tried to give up, the stronger my thoughts on Chizuru got.

After worrying, I made up my mind.

Trying to force you to give up just makes it extra hard. So let's just think of a thousand cranes for the rest of our lives. Even if one day she makes and marries a lover, she will continue to play The Ideal Brother, trying to keep an eye on her all the time...

I definitely think Chizuru liked her, even if she wasn't her blood-connected sister. It sounds very painful when I say "I really love my twin sister," but it wasn't any different to the feeling of liking the same class of girls to me. That's how I fell in love with nature.

I'm sure I was just lucky enough to be born as my twin sister and brother... and by telling myself yes, I managed to keep my mind normal every day.

"Damn...... I want you to be mine to wake me up every morning too. I can't help but rely on how familiar I am."

"Childhood tame? What are you talking about? You're my twin sister, aren't you?

"Huh? Look, what are you in love with? We've been friends since kindergarten, haven't we?

……!?

"Well, we do have the same age and the house is next door to each other, and the school grew up like it was today because we've always been together... but we're genuine red people. I'm not your sister, am I?

I saw a thousand cranes with a decent look on their face and noticed. He said this was a 'dream'.

Apparently, Chizuru in my dreams is my childhood tame setting. Looks like the desire I've been having from day to day has appeared in my dreams.

"Ah... oh, you did..."

"Weird look..."

Seeing me in a hurry to deceive, Chizuru gave me a strange look and sighed.

"... I was dreaming"

"A dream?"

"Oh. We were twin sisters and brothers in our dreams. And I was in love with you, my real sister.... weird dreams, huh?

"Become..."

When I told him what my dream was about, Chizuru started dyeing her cheeks red and wolfing.

"... no, you've had a terrific dream"

"Right...... But..."

"But...?

That's all I'm gonna say. I'm gonna shut up. And I almost said, "This is actually my dream..."

I don't know why, but the moment I put it in my mouth, I felt like I'd wake up from this happy dream. So I can't tell you the truth. I want to stay in this dream for as long as every minute and second.

"... nothing"

"You've been saying weird things just now.... but don't bother if you really are"

"Trouble?"

"Yeah. Because I... have long been about hope..."

Chizuru said so and caged his mouth, looking up at me in embarrassment.

……

"Oh, I'm sorry! Forget about that one!

Thousand cranes' eyes, returned so in a hurry, appeared slightly moist.

... Oh well. Do Chizuru in my dreams like me?

As soon as I realized it, I mocked myself without thinking, "What a convenient dream I have.

The real Chizuru naturally only thinks of me as his brother. Besides, she said she was dating her own best friend.

"Chizuru"

"What... what?

When I grabbed Chizuru's wrist and drew it toward me, I turned my hand around her back and held her tight with strong force.

"I liked Chizuru, too. Ever since I was a kid, I've always liked it."

"Of, look...?

Chizuru was turning his face bright red and complaining, "It's painful," but I didn't care and kept holding her tight.

I don't mind dreaming. I would now like to convey my grand thoughts to Chizuru, a relationship of 'childhood taming'. I want to love her without feeling backward.

"I love you more than anyone. Absolutely, because it makes me happy... so I want you to stay by my side all the time"

"... yeah. I like hope more than anyone else, too. We'll be together forever."

That's how we were checking each other's feelings, and I could inadvertently hear him calling his own name from above.

"-Watch!

"... mmm..."

"Look, wake up!

When I opened my eyes, I saw Chizuru peering into my face.

"Look, it's morning!

"It's morning..."

So whining I wake up on my upper body, rubbing my sleeping eyes and holding my head with one hand. It seems that she is not tired due to lack of sleep.

And at the same time, he makes me realize again, "Was that a dream after all," and I feel like I'm not going to hang up.

"Morning, look!

"... good morning"

"Breakfast is already ready, so get dressed quickly."

"Oh, okay"

Returning it, Chizuru turned his back and tried to get out of the room.

Our aunts and wives who took the twins are rare to face each other, even though they live in the same house at once. Mostly because he came home late at night and by the time we woke up, he was already out of the house.

Chizuru is in charge of our chores on behalf of our busy aunts. I always say, "Let me help you," but they say, "Let me do this much," and they say no.

"Chizuru"

"Hmm? What's going on?

Unexpectedly, Chizuru, with his hand on the door knob, looked back at this one.

"We're sisters and brothers...?

"Huh!? You bet, right?... Could it be that you're sleeping in love?

"Oh, no... for some reason, I dreamed Chizuru had become a familiar child living in the house next door"

"Oh, yeah! What was I like in the dream?

"It's..."

I can't possibly say what my dream is about Chizuru, who asks me intrigued, and I get stuck in words. What would she look like if I said, "You in a dream were both my thoughts"...

……

"Look...?

"Well, the... nothing was the same as usual"

"Oh well. But... if it was me and Hope, even if we weren't sisters and brothers, we would have gotten along."

Chizuru said so as to whine, returning a soft grin at me upset.

"Well, I'll be ready."

When Chizuru called me like that, he opened the door and left the room.

Hurry up and get dressed. I'll head to the living room with quick feet and sit back in the chair.

Then a thousand cranes in the kitchen looked back at this one and walked towards the table.

"Yes, look."

Suddenly, Chizuru offered me a box wrapped in beautiful wrapping paper.

"... What's this?

"Look, it's Valentine's Day, right?

That's what they give me back, and I remember that today was Valentine's Day when they said, "Oh, you did, if you say so".

Chizuru gives me this handmade chocolate every year. While my head understood that it wasn't fatal chocolate, I was glad it seemed like something special.

"Thank you, Chizuru"

"Yeah. To my hopes, because I've always been a nuisance...... about these days, I want to shape my gratitude. Because I'm only good at cooking and making sweets.... I'm clumsy about other things."

With that said, Chizuru smiled bitterly.

I said to Chizuru, "Can I eat now? When I asked," Fine, "I opened the wrapping paper, took out a grain of chocolate in the box, and threw it into my mouth.

"I don't know...? Delicious?"

"Of course. Aren't your arms up again?

With that said and praised, Chizuru scratched his cheek with his index finger as it lit up.

"Oh well...? Would you be happy?

Seeing a thousand cranes with a floating look as I said so, my mouth movement stops as I chewed the chocolate.

Moving his gaze over the edge of the table, he noticed that there was another wrapped box. Will you give this to me later?

"What's wrong...?

Chizuru, realizing that something was wrong with me, looked strange and asked me that.

"Oh, oh... bad. Right...... so delicious, I'm sure he'd love it too"

Replying so, I suppress jealousy and force myself to make a smile. Chizuru, unaware of my feelings, smiled innocently gladly when she heard it.

With her on the side like that I picked another grain of chocolate with my finger and carried it straight to my mouth.

That chocolate made by my beloved tasted sweet and uncut tears.
