Miyeon's Transformed Body
The Team Valkyrie's beach vacation had ended on a sour note, unexpectedly disrupted by a Kraken attack.
Thanks to Kang Cheonhu's sudden intervention, the Kraken went down without much trouble—but at the cost of Jinseok suffering a serious injury.
Still, Ye-eun's healing had mended him swiftly, leaving no lasting wounds or side effects. The real damage was to his spirit: charging at Kang Cheonhu only to suffer a humiliating, one-sided defeat had carved a deep emotional scar.
"I'm still so far from ready... Ngh."
To Jinseok, Kang Cheonhu now loomed like an unbreakable wall. And that was the cold, hard truth.
No sooner had he recovered than Jinseok was back in the gym, pushing himself to the brink with sweat-drenched workouts. But no amount of training could shake the sense of his own limits. He'd thrown everything he had at Kang Cheonhu, only to fail to scratch him and get flung aside like trash. He'd meant to shield Miyeon, yet she'd ended up protecting him—along with Serin and Ye-eun. The sheer patheticness of it all filled him with crushing self-loathing.
"Jinseok. You okay?"
"Serin?"
Jinseok was catching his breath after his session, drenched in sweat, when Serin appeared, her face etched with worry. She'd noticed how mentally battered he was and had come to check on him.
"What's up all of a sudden? Showing up in the training facility like this."
This was Team Valkyrie's state-of-the-art training complex. The base wasn't on the absurd scale of Team Tempest's, but as home to S-rank heroes, it sprawled across nearly an entire building, packed with top-tier facilities. Jinseok's gym was like a high-end fitness club, loaded with equipment—though he was the main user. It was customized for his Physical Enhancement ability, with machines built to handle insane weights. Everyone had their own specialized training rooms tailored to their powers, so cross-visits were rare. Serin had her own dedicated space, of course.
"You've been training way too hard lately, Jinseok. It worries me. Even for someone with abilities, pushing like that isn't good for your body."
"I see. Sorry for making you worry."
Hearing that Serin cared so much softened something in him, and he apologized for putting her through it.
"Why the sudden training obsession?"
"Ever since the beach incident, I've just felt... weak. Like I can't go on like this."
The massive gap with Kang Cheonhu had hit him hard, exposing his frailty and leaving him drowning in shame. Sure, he'd always known S-rank heroes like Miyeon, Serin, and Ye-eun were leagues above—watching them up close had drilled that in. But charging at Kang Cheonhu and getting dismantled without landing a blow, treated like garbage... that drove the power disparity home like nothing else.
(And getting protected by everyone? mortifying.)
Not just beaten by Kang Cheonhu, but needing help from Miyeon, Serin, and Ye-eun? It stung with embarrassment. He'd screwed up royally and dragged everyone into saving his ass.
"Mm. But I think you're plenty strong already, Jinseok. Please don't beat yourself up over it. Especially since your heart is so strong."
"Huh?"
"A normal person—or even someone with fighting skills—wouldn't have rushed to protect your sister from someone as terrifying as Kang Cheonhu. That's what I love about you... how kind you are."
"Serin..."
Serin comforted him, explaining that his inner strength was exactly why she loved him. Her warm words eased the tightness in his chest a little.
"Hehe. Guess I spilled one reason why I like you."
"Serin. Thank you."
He pulled her into a tight embrace. "And how reliable and strong you are, too."
Jinseok felt her love enveloping him, and Serin melted happily into his arms.
Whiiiir!
While Jinseok and Serin were lost in their sweet moment, Miyeon was at the hospital under exclusive contract with Team Valkyrie, undergoing a full-body scan.
Heroes often exhibited unique physiological traits beyond normal humans, so most had dedicated physicians. Miyeon had a female doctor assigned as her primary care physician.
"Everything looks normal."
"I see. Thank you."
The doctor reviewed the scan data and gave her diagnosis. Having treated Miyeon for years, she was intimately familiar with her baseline vitals—and nothing seemed off.
"I saw the footage, but you fought alongside Kang Cheonhu, right? Taking his power into your own body... Doing something that insane and coming out unscathed? Your physique is incredible, Miyeon."
The doctor had watched the beach battle clips circulating online—plenty of bystanders had captured it on smartphones. That tentacle-tentacled creep who'd grabbed Jinseok's ankle had even uploaded his own video to his channel, only to get buried in hate comments. Conveniently, no footage existed of Kang Cheonhu kissing or groping Miyeon; his sandstorm had blocked all visibility and recordings.
Miyeon hadn't breathed a word of it to anyone, claiming she'd simply talked him into teaming up.
The doctor had seen Miyeon absorb Kang Cheonhu's massive lightning strike through her body to obliterate the Kraken in one shot. For an ordinary person—or most heroes—that would've been suicidal. Yet Miyeon had emerged fine.
But not entirely. Something had felt off in her body ever since, prompting the checkup.
"With Ye-eun's amazing healing on Team Valkyrie, I figured you wouldn't need a formal diagnosis. Something wrong?"
"Hm..."
Miyeon had gotten healed by Ye-eun after Jinseok, and it was more effective than any hospital. The lightning damage was gone; no pain or discomfort lingered.
"My body feels... a bit more sensitive."
"More sensitive?"
"Ah... My senses are heightened in a weird way. Especially... um, in more embarrassing areas..."
"You mean... like, sexually?"
Miyeon hesitated even in front of her long-time doctor, cheeks flushing. The physician picked up on it, piecing together what she meant.
"Your sexual sensitivity has increased?"
"..."
Miyeon nodded silently, face burning.
Ever since teaming up with Kang Cheonhu, her entire body's erotic sensations had spiked inexplicably. Her skin tingled hypersensitively overall, but her breasts, ass, and pussy felt exponentially more responsive—like her pleasure nerves had been amplified several times over.
It was mortifying for her.
In truth, it stemmed from absorbing Kang Cheonhu's lightning. He'd slyly tuned it to supercharge her sensitivity, rewiring her nerve cells across her body to heighten pleasure responses. Not an injury, but a fundamental shift in her neural sensitivity—beyond even Ye-eun's healing to reverse.
Miyeon was struggling to suppress it, but inwardly, she was deeply troubled.
"That's odd. I can't detect anything unusual."
Standard medical scans couldn't pick up such subtle neural tweaks. Her doctor was baffled; amplified sexual sensitivity was unheard of.
