I've Liked Oppa Since Long Ago Too...
The two women had been splashing around joyfully in the pool for quite a while before Lee Soyeon and Shin Da-hee finally took a break, looking a bit worn out. They lay side by side on the wide rectangular pool float that Soyeon had been leisurely enjoying, basking in the relaxation.
Suddenly, Da-hee turned her head toward the distant sunbed, letting out a soft gasp. With a voice tinged with shyness, she called out to Soyeon.
"Whoa, wow... Unnie, Soyeon unnie..."
"Yeah...? What's up, Da-hee?"
"Over there, look over there. O-Oppa and Gayeon unnie... the two of them...!"
Da-hee cutely covered her face with both hands. Soyeon's gaze naturally shifted to the couple on the sunbed. She watched the pair exchanging massages without much fuss and muttered under her breath.
"Ah, she's at it again. That damn per—mmph!"
As usual, she was about to trash-talk Kim Gayeon, calling her a pervert or whatever, but she suddenly remembered the barely legal girl lying right next to her and clamped her mouth shut.
Soyeon was too late to play it off, and Da-hee, who had been embarrassed by the sight, surprisingly didn't freak out. Instead, she asked calmly.
"Th-that...! So, you and oppa, and the unnies, you're all dating, right? Like, in a relationship...?"
"Ugh... Well, it was pretty obvious all along, huh? Thanks to that vixen?"
Soyeon made a troubled face and averted her eyes from Da-hee, who stuck out her tongue cutely and whined like a kid throwing a tantrum.
"Of course! I-I'm only a year or two younger than you unnies anyway? I know everything there's to know!"
"Uh, yeah... You're right about what you're thinking, Da-hee."
This time, Soyeon turned her head away, looking mortified in front of the newbie little sister.
"Oh, but... um, unnie. This might be rude, is it okay?"
"Yeah? What is it? Go ahead, be comfortable."
Soyeon figured it was something like why the three of them dated Hyun, or why he had a harem, or if it made sense as a woman—questions like that. But Da-hee hemmed and hawed even after being told to speak freely, piquing Soyeon's curiosity even more. She prodded her directly.
"What's wrong, Da-hee? I said you can speak freely. What are you curious about?"
"W-well..."
Da-hee swallowed hard at Soyeon's urging and whispered in a tiny voice.
"Outside, at the shelter we lived in... Ho-guk oppa, Na Ho-guk oppa... and you, unnie... were you guys like, f-flirting? S-something like th—mmph?!"
Before Da-hee could finish, a panicked Soyeon clamped her hand over Da-hee's mouth and hugged her tight, leaping off the float together.
"Kyaa?! U-Unnie?!"
"Who said that?! Jisoo unnie? Or some other girls?!"
"F-First, Jisoo unnie...?"
"That's all lies! Lies! Flirting...? Ridiculous! Sure, Ho-guk oppa's a good guy with skills... He's combat-focused unlike our Hyun oppa, so he's reliable out there, but... anyway, absolutely not!"
Soyeon rattled it off like a machine gun, then—in their current predicament of bouncing off the float and splashing back into the water—hugged Da-hee from behind in a back hug, pressing her further.
"He was just a nice guy... yeah, like our Hyun oppa to you, Da-hee. Nothing like flirting...! And I never did any skinship with that Ho-guk oppa, nothing at all? My first kiss and losing my virginity were both with Hyun oppa. So don't misunderstand, okay?"
This was a far cry from the gentle, kind Soyeon Da-hee had known over the past three days. Suddenly turning into a scary unnie, her over-the-top reaction made Da-hee tear up a little as she replied.
"Eek! Y-Yes! Sorry, unnie. I-I'm sorry...!"
"...Ah?"
Soyeon snapped out of it at the apology, quickly spinning Da-hee around for a proper front hug.
"Ah, geez... Jisoo unnie, seriously. What a jerk, joking like that...! Next time I go out to Jeongsu-gu, I'll set her straight. Sorry, sorry. Our good girl Da-hee. There there. Mwah, mwah!"
Just like how Hyun often treated Da-hee—babying her with cheek kisses—Da-hee wiped her eyes with her fingers and looked up at Soyeon with a more cautious expression.
"Th-then... unnie. Does that mean I can become oppa's woman too?"
"Ah...? What? Th-that... probably not?"
"Why? Th-there's only oppa, you unnies, and me here... And I'm an adult now..."
Da-hee fidgeted her fingers together, her cheeks flushing girlishly. Soyeon couldn't help but slap her forehead and sigh inwardly at the maidenly reaction.
Damn, what the hell has that pervert Gayeon been doing to her these past three days?!
Of course... Hyun's special awakening ability kept the hotel running, but unlike regular women who just took supplies with points and left, only the pretty, beautiful ones who caught his eye could stay permanently.
Gayeon had relentlessly gaslit Da-hee over the past three days, drilling that into her head. In this fucked-up world, what was wrong with a capable guy like Hyun building a harem? He even generously gave supplies to other women. And he didn't force the pretty ones to stay—he gave them a choice, so it wasn't bad at all...
That kind of brainwashing, nonstop for three days. And now Soyeon was witnessing the results right in front of her eyes.
She glanced back at the sunbed, sighing inwardly again.
No, the vibe so far made it seem like they'd just get along as normal siblings. Why make her a rival...? That lesbian pervert!!!
At Soyeon's frustrated inner outburst, Da-hee turned back to the sunbed too—and this time, she really jumped, gasping in shock.
"Eek...?! U-Unnie, that, no way... A-Are they really doing it?!"
"...Don't look. Good girls like you, Da-hee, aren't ready for that yet. No no!"
Paying no mind to the two watching, Gayeon had her legs spread wide, locking Hyun's waist and refusing to let go in her lewd play. Was she doing it on purpose? Her moans—ahn ahn—carried clearly all the way to their distant spot.
Anyone older than a little kid could tell those two weren't wrestling—they were fucking. Wild, bestial thrusts anyone could recognize.
Despite Soyeon's half-hearted scolding, Da-hee sneaked peeks at the pair. She gulped hard and turned to Soyeon.
"...Unnie!"
"Y-Yeah? What is it, Da-hee?"
"I wanna do that with oppa too. Just like you unnies... I wanna be oppa's woman. I've liked oppa since long ago too..."
"...Hah, hah. Oppa, Hyun oppa..."
Hyun looked down at Kim Gayeon, collapsed limp and exhausted on the sunbed. He cautiously side-eyed the two women behind them—Soyeon and Da-hee—to gauge their reactions.
Even he thought fucking right in front of Da-hee was a bit much... But they'd be living together here forever anyway; no point hiding it. Da-hee already seemed to have guessed their relationships over the past three days. Better to be upfront from the start and show her his harem life directly—that seductive logic from this slutty fox had gotten the better of him.
No, even so, this feels kinda wrong... Did I get too caught up in the mood?
Pondering half-heartedly, he pulled an Undine's Droplet from his inventory to purify Gayeon's pussy, then helped her back into her micro bikini.
"...Yeah. Since we're already doing this, like you said, we should go all in. Go switch with Soyeon."
"Hng... Y-Yeah. Good call, oppa. This is right. Da-hee's an adult now... Hell, even as a high schooler, she knows what there is to know. Hiding it would be weirder. And..."
Gayeon trailed off mid-afterglow. Hyun shot her a look to spit it out. She continued with an awkward expression.
"Oppa isn't usually this soft, right? Think back to when you first fucked me..."
"...Yeah, fair point."
Ever since taking in Gayeon and Soyeon—women who satisfied him completely—had his sharp edge from the regression's early days and the apocalypse's start dulled too much lately?
And now, with Da-hee—his first timeline connection—becoming his little sister too...
Well, I'm human too. Without crises, people naturally soften up.
Gayeon's sharp observation made him pause, but his abilities weren't going anywhere. This second round was for enjoying harem sex life and plowing decent bitches—no changes there. No need to overthink.
He smacked Gayeon's ass and grinned.
"Yeah, that was me back then. Now go fetch Soyeon quick. Time to rearm mentally—I'll fuck you both properly right here."
