Part 1: A Strangely Thrilling Vibe
'This feels so strangely thrilling...' Standing side by side with her washing dishes like this, it was almost like we were a newlywed couple. The clinking of the plates bumping together stirred up an odd excitement in me.
A wife like Jina, huh. The thought alone made the less-than-an-arm's-length distance between us suddenly impossible to ignore.
But it seemed like I was the only one bothered by it. Jina had been silently focused on scrubbing bubbles onto the dishes ever since we started.
'Well, yeah...' Of course it would be like that. I'd been living with the Yoo family since I was ten as Lee Yu-han, which meant we'd shared a home for a solid twelve years. That was more than enough time for her to see me firmly as her "little brother" above all else.
By now, in Jina's mind, Yu-han was probably locked in as the "precious little brother I have to protect." The same went for Sena and Gayeong—though for Gayeong, he was more like a son than a brother.
To advance things with them, I'd have to break through that wall first. Only then could I hold hands, kiss, or fuck without it feeling off.
Of course, it wouldn't be easy. This wasn't some flimsy one- or two-year bond—it was twelve years of buildup. I couldn't even imagine how tall and thick those walls must be.
'Gotta start small and work my way up...' My instincts screamed to pounce on all three of them right now, but I wasn't some wild animal giving in to base urges.
'Man...' She smells amazing. Should I ask what body wash she uses? Jina gave off this incredibly refreshing scent. I was savoring it discreetly when—
"So, why the sudden interest in working out?"
I still had a ton of dishes left, but she'd already finished scrubbing and was yanking off her rubber gloves as she asked.
"Eh... just felt like it?"
"'Just felt like it'? Yeah, right."
She snorted like I was talking nonsense, then her eyes suddenly sparkled. "Hmm. Got a crush at school or something?"
"Classmate? Senpai? Oh, or a kouhai?"
Her narrowed gaze stabbed right into my face.
'Whoa...' Almost reached for my wallet. No joke—my right hand was already in my back pocket. If my wallet had been there like usual, I'd have whipped it out and handed it over. That look in her eyes was sharp.
It reminded me of her high school delinquent days, when she'd bully the snot-nosed kid version of me out of my precious 5,000 won. I'd gotten a hug from her in exchange—lost forever, that cash—but it meant no Money Card for me, so I seethed with envy watching my friends decked out in cash shop items and pets.
'Fuck, they didn't even give snail pets back then...' But hey, thanks for it now, sis. Her embrace was still the best in my memories.
Her reaction just now was so intense it dragged up that mildly spicy episode from the depths. Why the over-the-top response? Jealousy? Nah, unlikely. More like curiosity about which "thieving bitch" had stolen her precious little brother's heart. Jina might be blunt and gruff, but she was always on Yu-han's side—the one she saw as "her little brother to look after."
Call it a slight siscon streak.
'Fair enough...' Thinking back to Yu-han's looks in the mirror, even I'd have gone full siscon if I were her. No—siscon? Hell, I'd have jumped him ages ago and fucked him senseless, just waiting for him to hit adulthood.
'How the hell has she held back?' As a sports-world woman, her sex drive was set higher than average. How had she resisted this long? Probably the settings: every time she saw Yu-han and her womb throbbed with lust, that "little brother I must protect" imprint—brainwashed-level deep—kept her from pouncing.
I nodded inwardly and grumbled back in a surly tone. "What're you talking about? Just feel like I've put on some weight lately."
"Trying to lose it?"
"Eh... yeah, it'd be nice."
"Nah, you need to gain some."
"Whatever. You gonna teach me or not?"
She paused, shaking off nonexistent water from her hands, then flashed a playful smirk. "What if I don't?"
"Then... guess I'll just sign up at some local gym."
Right then—her eyebrow twitched. Like something didn't sit right.
"Forget it. Waste of money. Just come to my gym. Can't promise regular sessions, but I'll train you whenever I can."
"For real?"
"Yeah."
She grinned, nodding proudly. "I don't usually do this kinda thing... You know how much one PT session with me costs?"
Obviously pricey. Jina was a famous trainer even celebrities and models sought out.
"Perks of family, right?"
I lightly tapped her arm in thanks, and she flinched.
What the—? Her face flushed red. That wasn't a "big sis" reaction. No sister in the world blushes like that from her "little bro" touching her arm.
'No way...' Had her siscon evolved into full-on lust for her "little brother" Yu-han?
"Ahem. So, what's your goal?"
"Goal?"
"Y'know, drop X kilos or whatever."
"Hmm..."
What to say? I thought for a sec, then lifted my arm slightly toward her.
She gave me a puzzled look.
"Feel it."
"W-what..?"
She coughed to cover her fluster, then cautiously reached out.
Squishy-soft. That's probably what she felt. Addictive, no doubt—her mouth hung slightly open.
Pretending not to notice, I flexed.
And... nothing. No change.
"What? That your flex?"
I could practically hear what she swallowed: Are you scared I'll hurt your feelings?
"Yeah..."
"Definitely... serious."
She was right. Even by this world's male standards, it was subpar. I'd collapse after a couple thrusts during sex, no doubt. Sure, most guys here just lay there while women took charge—but as a man, I'd be the one fucking, not humiliatingly pinned beneath some woman mewling.
'Men need strength.' Damn straight. What good was shop-boosted virility without the muscle to back it up?
So my goal: stamina to outlast a woman, no exhausted whimpering first. Realistically... who knows. But I had the goddess's shop. A thorough search might turn up something useful.
I lowered my arm, and a flicker of regret crossed her face—robbed of her toy. She shook it off quick, nodding at me.
"Got it. I'll tell the desk."
"When you wanna start?"
"Tomorrow."
"Cool, we can head out when I go in for my shift."
"Works for me."
That wrapped up our chat. True to "strike while the iron's hot," she headed to her room—probably to call her gym right away.
I finished the remaining dishes and, instead of my room, went to the one directly opposite hers.
'No one's watching...' Perfect. I'd volunteered for dish duty just for this moment. No onlookers, no hesitation.
Heart pounding oddly, I quietly opened the closed door and slipped into Gayeong's room.
A warm, cozy scent hit me—making my pulse race harder. Totally different from Yu-han's room, it really drove home that I was sneaking into someone else's space.
Like back when I was a snot-nosed kid, sneaking into my parents' room with impure thoughts after picking up dropped items one too many times—that thrill resurrected from the grave as I slowly scanned the room.
'Laptop... where is it?'
There you are. In my old world, guys guarded their PC hard drives and phones like Fort Knox. Here, women did the same with their computer's hidden "oppa" stash—more precious than life.
And Gayeong had a specific setting: when lust struck, she'd soothe it with dirty videos. Utterly normal for this world's women.
That's why I snuck in today. To check 'her tastes.' What kind was her poison?
Porn wasn't all the same—genres existed: humiliation, softcore, intense lovemaking, group stuff, molester fantasies, etc. Knowing her go-tos meant uncovering her fantasies and fetishes.
Nail that, and it'd be like an open-book exam.
'C'mon...' Boot up already. Damn, this thing's slow—will vids even play? Nothing more frustrating than a stuttering go-to during self-love. I pondered gifting her a beastly new laptop as filial piety when it finally finished booting.
I hit enter on the familiar icon.
Password prompt—not the desktop.
'Tch...' Figured her age might mean no lock, but nope. With "oppas" inside, of course she'd password it.
'Password...' What could it be? I balanced the laptop on my thigh, guessing. Common: name plus numbers. Tried Yoo Ga-young, Gayeong—wrong.
Birthday? When's hers? She'd weep if she heard—ungrateful brat after raising me—but I'd only been Yu-han a few hours. No settings for that anyway.
But Yu-han's phone? I closed the laptop gently, slipped out—carefully—and headed to my third-floor room.
Powered on the phone, checked calendar first.
Bingo. Red stars marked dates from January to December: Gayeong May 17, Jina July 2, Sena December 24.
'Damn, poor girl.' Born on Christmas Eve? While others got birthday and Christmas gifts yearly, Sena got shortchanged—birthday-slash-Christmas combo. Maybe doubled up, but strict Gayeong? Doubt it.
Should've set birthdays. Sorry, kid Sena who only got two hauls a year while friends got three (Kids' Day included). I pocketed the phone and headed back downstairs, heels clicking.
None worked. Gayeong0517, Jina0702, Sena1224—all wrong. Tried numbers alone, added/multiplied—nada.
'No way...' Then it hit: untried combo. Yu-han0920.
Skeptical, I typed it. Ding!—desktop appeared. I killed the sound quick.
'Anyway...' Past security. Time to hunt. She wouldn't leave it lying around, but amateurs are easy to crack if you know the tricks.
Years of hiding stuff made me a pro finder now. Felt weirdly nostalgic as I tried everything.
But... nothing? No porn folder. Streaming history spotless too. Sage mode last night?
Reluctant, clicking idly—then I spotted photos and docs screaming "not Gayeong's."
'Ah.' Shared with Jina, probably. No way she'd risk her daughter finding her "oppa" stash—ultimate mom shame.
So, the ark. Where? Checked laptop bag—nope. Gut feeling: mattress bottom. Slid hand under...
'Bingo.'
Cool, hard texture gripped my palm. Plugged into the PC...
'Oh yeah...'
Instant revelation: Gayeong's cute looks hid a taste for the extreme. The thumbnails alone—curated collection?—reeled me in, head spinning.
