A Man Who Lost Confidence, to a Gentle Chastity-Reversed World - Chapter 80: Observatory Date, Our Story

Chapter 80: Observatory Date, Our Story

The observatory, looking like a flat dorayaki from outside, feels surprisingly spacious inside. Yuki smoothly pulls my hand, leading me to the window.

The distant city glows with countless lights, signaling human activity. Watching the almost-illumination, Yuki speaks.

“…It’s kinda amazing, right? So bright even at night.”

Her wistful tone focuses on the lights. I can only nod, “Y-Yeah…” but she doesn’t seem disappointed, continuing to talk.

“It looks totally different at night… so sparkly, like another world!”

She links her arm with mine again. I flinch, but she giggles, “Ehehe,” smiling shyly.

“Is that okay?”

It’s not bad—I shake my head to show it. My exaggerated head-shaking is lame, but she looks at me happily.

“Wanna walk around slowly?”

Her upward glance and the soft pressure of her arm are overwhelming. Whether intentional or not, she never shies from such contact.

A teenage girl should be embarrassed to be seen with her brother. It’s my bias, but siblings often care about that. In my old world, my sister avoided me, I think.

“Look, Shun-nii, don’t get lost!” Yuki says, mindful of other visitors. I’m still scared of how people see our closeness, but her willingness to be close makes me happy, and I let myself be swept along.

As we walk slowly, she points out, “That’s the sea, right?” or “I haven’t been there.” I don’t know these places, so I give vague replies.

I should’ve researched the view, but I only learned we were coming today. As I think this, Yuki points far off.

“Shun-nii, it’s dark, but I think our house is around there.”

The residential area isn’t bright, but distance-wise, it fits. Yuki, a local, would know.

“So many lights, so many people living there,” she murmurs, looking up at me. I’m still not used to a beautiful girl’s repeated gazes.

“With all these houses, being born in the same one as you feels so lucky. And going on a date like this… I’m really blessed!”

Her words stun me, leaving me unsure how to respond. Normally, being my sibling would feel like a punishment, but she says this.

Her kindness pierces my heart. I can’t hide my feelings for her, even if they sound creepy.

“Y-Yeah, I-I’m… glad we’re siblings too…”

It’s true but feels unworthy coming from me. Yet she accepts it with an “Ehehe!” clinging tighter to my arm.

Not just her soft chest but her warm upper body presses against me. Her sweetness is precious, but I must stop my impure thoughts.

After circling the observatory, we sit on an empty bench inside, where the view is less clear but seats are free.

“Shun-nii, you okay? Not tired?” Yuki worries about me. Maybe in this world, I never came to such places.

It’s not too crowded, and we can sit, so it’s manageable. Maybe tourist spots here have fewer people.

“Y-Yeah, I’m fine… s-sorry, it’s your birthday, and…”

I’m worried about because I’m a guy and seem frail. I don’t know about men’s stamina here, but mine’s like my old world’s.

“No, it’s fine. I’m sticking so close, so I was wondering if you’re okay,” she says, looking concerned. On the bench, we’re close but not touching now.

“N-No, I don’t mind at all… i-it makes my heart race, but…” I say, creepy and inappropriate for a sister. Being flustered by closeness is a virgin’s mindset, and I might be misunderstanding.

“Doki-doki, huh?” Yuki says, sounding relieved, and continues.

“…You’ve really changed, Shun-nii. Before high school, you seemed scared of girls and kinda distant with me.”

Her words startle me. I don’t know middle-school me, nor if I’m acting right now. I recall I was dismissive with her back then.

Swinging her legs, she touches her lips, recalling.

“When you chose the co-ed school nearby, I was happy we might be together but worried if you’d be okay.”

A brother worrying his sister is pathetic for a guy. But maybe in this world, men are seen that way, a convenient thought.

“But now, you’re close with Asagi-san and Maki-san! And you’re on a date with me like this.”

Blushing slightly, she looks down.

“So, thanks, Shun-nii!” She flashes a radiant smile, pure and cute, making my heart race repeatedly.

But I lack confidence to be the great brother she deserves. She once asked to be treated like a lover, but I’m unsure if I’m doing that.

“I-I’m the one… who’s always helped by you, Yuki… s-so…” I stammer. I don’t know what I’m doing for her, but I’m certain I owe her thanks.

Frantically, I put my bag on my lap, pulling out a small package. It’s not smooth, maybe mistimed, but I muster a bit of courage.

“I-It’s a birthday gift… i-it’s not much, but…”

The shop wrapped it nicely, but I’m unsure if it suits her. I offer it nervously.

“Eh, S-Shun-nii?” Yuki says, surprised, but takes it. I can’t meet her eyes, fearing she’ll think I’m overstepping.

“…Can I open it?” she asks. I nod slightly.

She unties the ribbon, “shuru-shuru,” and takes out the contents.

“…A pendant… you picked this?” It’s a four-leaf clover pendant. I chose it based on the simplistic idea that girls like accessories, the only thing I could think of.

I considered a heart but felt it wasn’t my place, settling on a clover, symbolizing my luck in meeting her. I can’t tell her such childish thoughts, though—it’s not my place.

“W-Will you… accept it…?” I ask, anxious as she stares at it. If she thinks it’s unfit for her birthday, that’s that.

She holds it tightly in both hands, then smiles brightly.

“Of course I will! Ehehe, I’m so happy, Shun-nii…!”

But instead of putting it away, she hands it back.

“Shun-nii, can you put it on me… please?”

The tags are off, so it’s ready to wear, but it means touching her. Still, I can’t refuse her request, so I take it.

She closes her eyes, leaning forward, waiting. My arms tremble, heart pounding, but I carefully place it around her neck. When I let go, she giggles, “Nihehe,” smiling shyly.

Her silky hair and delicate shoulders linger in my touch. She pulls me up, seeming even livelier.

“Let’s look at the night view a bit more, Shun-nii!”

Taking my hand, she naturally links arms again. A date with a bright, sparkling girl keeps melting my heart.

After another loop, Yuki checks the time and suggests, “Shun-nii, it’s getting late. Wanna head down?”

She wants to browse the mall below, then go home to hang out. My fear that she found the date boring is swept away.

“I shouldn’t drag you around too much, and I wanna chat at home. If you’re not tired, is that okay…?”

I should be grateful she wants to spend time at home. I don’t deserve to be picky, and she shouldn’t worry.

If she wants to talk, I must respond, even if I’m bad at conversation.

“Y-Yeah, if that’s what you want, I’m totally fine,” I say. She smiles, messaging Mom on her phone about heading back.

“Wanna grab souvenirs downstairs, then go home?”

I nod, and she pulls my arm. After picking souvenirs and wandering, we head to the station with the crowd.

It’s around 8 PM, and the train’s filled with office workers. Not packed, but tight, so Yuki and I are close.

“Sorry, Shun-nii, it’s a bit cramped,” she apologizes for misjudging rush hour. But I’m hyper-aware of her soft body leaning against me, her scent and touch overwhelming.

Saying “back off” would avoid impure worries, but I can’t. So I talk with her, look out the window, and endure until our station.

The night residential area, lit by streetlights, feels different but not scary. In this world, men rarely go out alone at night, making my presence unusual.

Yet Yuki’s beside me, chatting brightly. Her willingness to engage without disliking our date is truly reassuring.

“Mom got a cake, so let’s eat it when we’re back!” she says, treating me as family. My sexual gaze is my own fault, and I can’t act on what she doesn’t want.

Her soft chest pressing against me, her happy smiles—it’s all sibling affection. Misinterpreting it is my perverse, disgusting thinking.

At home, Mom waits in the living room, and we eat cake together. It’s past 9 PM, so Yukari-san’s gone home.

“I wanted Yukari-chan to join, but she insisted on family-only time. I don’t want her to hold back, but she was firm,” Mom says, cutting a small whole cake.

“Maybe we should plan a group outing? It’d help us all bond,” she suggests. Being included is happiness itself, and I’d join unless rejected.

But what’s a family outing like? As I ponder, Yuki answers brightly.

“Then I gotta study harder!” Yuki says, licking cream from the corner of her mouth. It’s not deliberate, just a cute girl’s action, and I can’t help but watch.

After finishing the cake, Yuki takes my hand and declares to Mom, “I’m gonna talk with Shun-nii now!” Mom nods, “Sure, take your time. I’ve bathed, so you two shower when you’re ready,” and sees us off.

Humming happily, Yuki leads me to her room. Her space, unmistakably a girl’s, always makes me nervous.

“Shun-nii, sit next to me?” She pats the bed, inviting me. As I sit tensely beside her, she closes the distance instantly.

“…Is that okay?”

Her lover-like closeness and sweet, soft scent overwhelm me. How can a human emit such stimulating pheromones?

But she doesn’t mean it that way. Like a puppy, she snuggles, asking to talk—a precious, joyful request.

“You smell nice, Shun-nii… makes me wanna sniff more,” she says, nuzzling my neck with a “sunsun.” I can’t look at her, scared my cute, youthful sister might push me to do something erotic.

“…Shun-nii, can I talk about something?” she whispers in my ear. Her breath makes my heart race unintentionally, but I nod quietly.

“Y-Yeah, anything you want… it’s okay.”

My stilted words don’t make her laugh. She continues.

“You told me before that someone special will come for me someday, so I should save my first time for them.”

This topic strains my heart. My resolve to act on her feelings surges forward.

“I thought you were really thinking of me. So I considered it and observed the boys in my class to see if there’s someone like that.”

A girl like Yuki should enjoy fun, meaningful times with cool boys her age. Even if I want to keep her to myself, her life is her choice.

But she takes a breath and looks up at me.

“I still want you, Shun-nii. Not just as a brother, but your kindness, how you cherish girls—it’s only with you that I feel doki-doki.”

She once asked to be treated like a lover, but this confession nearly bursts my heart. Facing me, her serious yet trusting gaze captivates me.

“Of course, I’m happy you worry about me. But my feelings won’t change, so I wanted to tell you clearly.”

“You always worry you’re a burden, but you don’t need to. I want to be with you, and like I said before, I’m absolutely on your side.”

Having a girl who calls herself my ally so close, yet I keep running away. I should take a step toward her.

But unsure how, she continues.

“Oh, but, um… asking you to take my first time… don’t force yourself. I mean, a girl like me might not make you feel that way.”

“I’m already spoiled so much. So whenever you’re ready, it’s fine.”

Making my sister say this makes me pathetic. With Asagi-san, Maki-san, and Yukari-san, I’ve been passive, only acting when they prompt me.

Yuki’s been wanting this with me. I’ve avoided it, fearing it’s not her true desire or that it’s wrong with my sister, using my anxieties as excuses.

“…Yuki…!” I blurt out.

If she wants this and I don’t respond, my existence is worthless. I can’t bear her belittling herself either.

“Shun-nii? Did I… say something bad?” My loud voice makes her look anxious. Making her feel that way on her birthday proves I’m a terrible brother.

What I’m about to say is awful for a brother, but I can only be honest with the Yuki who stays kind to me.

“I-I don’t want you to say ‘someone like me’… I-I could never not feel that way about you…!”

I don’t know if it’s okay to say, but since she chose me over other boys, I need to tell her.

“Y-You might think it’s gross, but… I see you as my precious sister and a cute girl. Just being near you, I-I think erotic things…”

I lower my head, eyes down, but try to let my voice reach her clearly.

“But I’m scared I’ll mess up your life… though that’s just me being a coward, and, um…”

Losing what I want to say, I choose to be raw instead of clever.

“I-I know it’s greedy with other girls, and it’s wrong to lust after my sister, but…!”

My final words spill out.

“I-If you want it… I want to do naughty things with you… I’m sorry for being selfish…!”

I’m utterly selfish. Despite multiple lovers, I want to possess a cute, kind girl who shows me affection.

I’ve been indulging in her offer to take her first time. Today, all my feelings are laid bare.

“…Don’t apologize, it’s okay, Shun-nii…!” she says, and I look up. Despite deserving scorn, she gazes at me happily.

“I’m so happy… I really love you, Shun-nii…!”

Her “love” hits me with overwhelming doki-doki. I fall back—not forced, but gently pushed onto the bed by her.
