Prologue
The midsummer sun blazed mercilessly, its dazzling rays painting visions of vibrant vacations for the popular crowd or scenes ripped straight from an H●TLIMIT music video—scorching heat, a stunning girl in a risqué swimsuit.
A world utterly alien to a loner like me.
A loner’s summer vacation should mean holing up in an air-conditioned room, crunching on ice cream, and grinding through a backlog of games. That’s the gold standard. To outsiders, it might scream “shut-in NEET,” but for me, it’s the peak of perfection. Or at least, it was supposed to be.
“—Hey, Ryouta? What’re you spacing out for?”
“Huh…?”
Yuria’s voice, light and teasing, snapped me out of my thoughts as I stared at the scene before me. She stood there, radiant in her swimsuit, the summer sun glinting off her.
A swimsuit… yeah, I wasn’t in my pitch-dark, air-conditioned sanctuary right now. I was at a sprawling leisure pool, roasting under the relentless sun, surrounded by the kind of outgoing crowd I’d normally avoid like the plague.
And the reason a loner like me was stuck in this haven for extroverts? There was only one explanation.
My gaze drifted to the trio of breathtakingly gorgeous S-class girls standing before me, each in a swimsuit that left little to the imagination. Miyama Airi, Ichinose Yuria, and Kuroki Rui—my classmates, the kind of girls who turned heads wherever they went. Their curves were impossible to ignore: full breasts, shapely thighs, and navels that drew the eye like magnets. Their bare skin gleamed under the sunlight, far more captivating than the swimsuits themselves.
“Hehe… Ryouta-kun’s just staring at us, totally zoned out,” Rui teased, a playful smirk curling her lips. “Could it be you’re captivated by our swimsuits?”
“W-Well, I mean…” I stammered, my face heating up.
“Ryouta, Ryouta! Let’s hit the waterslide first!” Airi chimed in, her enthusiasm bubbling over.
“H-Hold on!”
Before I could protest, my hand was yanked, and I found myself being dragged toward the waterslide by the trio of beauties. If this were last year, I’d be camped out at home, controller in hand, lost in a game. But this summer? My gaming time was a grand total of zero minutes.
Why? Simple. I’d made a promise—or rather, I’d lost a bet to Yuria. Now, I was at the mercy of these three for the entire summer vacation. That’s how I ended up here, dragged to this massive leisure pool under their command.
Still… getting to soak in the sight of this trio of gorgeous girls, admired by everyone, in their swimsuits? That was nothing short of a miracle. Even if I was here at their beck and call, monopolizing their company at the pool in the middle of summer felt like a dream too perfect to be real.
Was a summer vacation this paradisiacal even allowed?
Savoring the moment, I let myself be pulled toward the waterslide, the trio’s laughter ringing in my ears. My scorching summer with these three stunning girls was just beginning.
“Hey, hey, everyone! Don’t leave me behind!”
Oh, and Tanaka was here too.
