Chapter 7: Yu-mi's Neural Erosion
The fiancée who had given him an STD, Kim Yu-mi…
She scanned Sang-hyuk’s changed height and face from top to bottom, and her voice trembled slightly.
“You… what the hell. Your face and your height…”
“What exactly are you trying to say?”
Sang-hyuk snapped back.
“Oppa, were you always this handsome? Why didn’t I ever notice?”
“To know is to love, and to love is to see; what one then sees is no longer as it was before…”
Sang-hyuk recited a passage from Professor Yu Hong-jun’s My Cultural Heritage Exploration.
“I guess you never wanted to know me before, never loved me…”
Yu-mi snapped in an irritated voice.
“Stop acting all cultured. You know I don’t read books. And why didn’t you answer my calls?”
Sang-hyuk regarded Yu-mi for a moment.
He had to settle things with her one way or another.
“Come in. Come inside and let’s talk.”
Yu-mi hesitated briefly before following him into his one-room apartment. The soft click of the front door closing echoed through the quiet space. Only the indirect lighting Sang-hyuk had left on cast a faint glow across the living room.
Yu-mi sat on the sofa and looked Sang-hyuk up and down once more. Her gaze lingered long on his shoulders and face. It was a completely different attitude from before, when she would clutch her phone and talk without ever looking at him.
Sang-hyuk did not sit across from her. Instead he took the chair at the desk, keeping his distance as he began to speak.
“I have something to say.”
“What… what is it? Don’t suddenly make the atmosphere weird like this. It’s not like you, Oppa.”
Sang-hyuk exhaled shortly and opened his mouth.
“You gave me an STD.”
Yu-mi’s expression froze for an instant.
“…What?”
“I have syphilis. I’ve never been with anyone but you since the day I was born.”
Yu-mi’s mouth fell open. Words wouldn’t come right away. Her pupils flickered left and right. Her fingers pinched the hem of her pants.
“Th-that’s… I don’t have anything like that. Don’t go accusing an innocent person. Didn’t you pick it up at some bar and try to pin it on me?”
“Where would I have gotten money for bars? Everything I earned, I spent on you.”
“M-maybe… a sauna? Couldn’t you have caught it at a sauna? Or… from a public toilet seat or something…”
The rambling continued. Her voice rose higher and higher, and her eyes avoided Sang-hyuk’s.
“So you’re suspecting I did it with another guy… No, that’s not it… Oppa, are you sure you got tested properly? It could be a misdiagnosis. Hospitals these days are so sloppy.”
Sang-hyuk watched Yu-mi in silence. The longer her excuses dragged on, the redder her face grew, her breathing quickening. In the past, Sang-hyuk would have been the first to back down with a “Well, that could be.”
But now it was different.
“Caught it at a sauna? Who? Me? You know I have mysophobia and never go near places like saunas.”
Yu-mi’s pupils wavered.
“Or you caught it from that weird personal trainer you were texting.”
Yu-mi’s breath hitched. Her lips parted, then closed. No more words came out.
“Oppa, what does that matter? If there’s a disease, we just get it treated quick and love each other again…”
Suddenly Yu-mi threw herself at Sang-hyuk. She cupped his face with both hands and tried to force a kiss.
Sang-hyuk firmly seized her wrists and pushed her away.
“Don’t.”
“Why… why are you avoiding me? Oppa, let’s make up. Let’s work it out with our bodies. Okay? Like before….”
Yu-mi clung to his clothes. Her eyes were already moist. But there was more calculation than emotion in that gaze.
Sang-hyuk peeled her hands off and spoke coldly.
“I’ve finished treating the syphilis. The doctor told me not to have sex until my girlfriend finishes her treatment. I can’t.”
In that moment, a low, clear voice rang out inside his head.
Your body is immune to all sexually transmitted diseases and pregnancy.
“Wh-what? What do you mean by that? Are you saying I’m a eunuch? Me, a eunuch?!”
Yu-mi said with a blank expression.
“Oppa, what are you talking about? A eunuch?”
“No, I was just talking to myself. Anyway, I’m not doing it with you anymore.”
Sang-hyuk pushed Yu-mi away and stepped back.
“I have nothing left to do with you. We’re done. Go home.”
Yu-mi’s face twisted in an instant. Her eyes turned sharp.
“What… are you seriously saying you won’t marry me? I’m pregnant. I’m carrying your kid and this is how you treat me?”
Her voice grew louder.
“Should I go to your company and tell them? That you knocked up your fiancée and dumped her! I’ll report you to the police for rape!”
A woman with nothing left to lose was fierce.
“Yeah, I did it with other guys. So what? Did you expect me to live staring at that withered little pinky-finger dick of yours? And I gave you syphilis, so what!”
“Yu-mi, you…”
“But do you have proof? Do you have any proof? Does syphilis come with a watermark so the judge can tell whether you gave it to me or I gave it to you?”
“What did you say?”
“I’ll say you raped me and gave me syphilis too. Rot in prison, you little-dick bastard!”
Yu-mi started screaming at the top of her lungs. Sounds of things falling, of her slamming the table, followed one after another.
From next door came a protest loud enough to shake the wall.
“Hey, keep it down!”
Yu-mi paid no attention. She dashed into the kitchen and pulled out a kitchen knife. Hands trembling, she pressed the tip against her own wrist.
“I’m going to die! Because you abandoned me! It’s all your fault!”
The blade flashed under the light. Sang-hyuk’s brow furrowed.
“You raped me, gave me syphilis, abandoned me while I was pregnant, and stabbed me with a knife! I’ll report it to the police!”
Yu-mi grabbed her phone and moved to press the emergency call button.
Noise, threats, even a self-harm spectacle. It had already spiraled beyond any hope of control.
Then Valentine’s voice rang out once more.
The thing I used on Lee Yu-na yesterday? You want me to do that?
Sang-hyuk closed his eyes briefly, then opened them. And he slowly approached Yu-mi.
Yu-mi was panting, knife still in hand.
Sang-hyuk looked at her and smiled gently.
Yu-mi’s heart suddenly pounded, and her face flushed red.
“Come on, baby. Give me the knife. That doesn’t suit you. You know that.”
Sang-hyuk seized her wrist, took the knife, and lifted her chin to force her eyes to meet his.
And smiling softly, he thought,
Fall under hypnosis.
The moment she saw Sang-hyuk’s smile, Yu-mi’s pupils wavered for an instant, then her strength began to drain. The shouting stopped, leaving only ragged breaths. Her eyes slowly unfocused.
Sang-hyuk pushed her down onto the sofa as if laying her there. There was almost no resistance. Only a thin moan escaped between the lips of the hypnotized Yu-mi.
Sang-hyuk lowered the zipper of her pants and murmured low,
“…Shall we begin now. Will it work today like it did yesterday?”
Sex for domination and conquest had begun.
Once her underwear was stripped away as well, Yu-mi’s lower body was fully exposed. She was already slightly wet.
It was her hypnotized body reacting on instinct.
Yu-mi half-reclined on the sofa, looking up at Sang-hyuk with unfocused eyes. Her lips parted, only thin breaths flowing out.
Sang-hyuk spread her knees and settled between them. When he lowered his own zipper, his already rock-hard cock sprang free. Thick, clear precum was dripping heavily from the head.
A gasp of a moan escaped Yu-mi at the sight of Sang-hyuk’s member.
“Th-this was Oppa’s thing? Why did I keep thinking it was a little dick? This really went inside me before?”
Yu-mi’s eyes blazed with lust.
“And Oppa, since when did you get beads put in? Even after trying lots of guys with rings or beads in their cocks, I’ve never seen a man with beads this big.”
It seemed that under hypnosis, there were no secrets. Yu-mi babbled on about her experiences with men.
The moment that fluid touched Yu-mi’s entrance—
Her hips convulsed hard.
“Haaaah…!”
The instant the precum soaked into her skin, Yu-mi’s senses began to grow abnormally sensitive.
An aphrodisiac effect hundreds of times stronger than any drug raced up through her lower body.
Her vaginal entrance spasmed open on its own, and love juices overflowed in an instant.
Yu-mi’s pupils unfocused even deeper. Her breathing quickened, moans unbroken.
“Wh-what… my body… feels weird… too… sensitive….”
Sang-hyuk pushed the head straight in. The moment the slippery heat enveloped his cock, Yu-mi’s back arched off the sofa like a bow.
“Aaaagh…!”
Sang-hyuk slowly pushed all the way in. The five beads embedded in his cock scraped along Yu-mi’s inner walls one after another as they entered.
With each bead that passed, Yu-mi’s body gave a small convulsion.
Especially when the thickest bead scraped across her G-spot, her thighs trembled hard.
“Haa… ahk… something… feels like it’s scraping… weird… so good….”
Sang-hyuk began to move his hips.
Precum continued to secrete, driving Yu-mi’s sensitivity beyond all limits.
Yu-mi couldn’t even manage proper breathing. Her eyes rolled back, mouth hanging open with drool spilling out. Her hands clenched the sofa sheets tight. Her toes curled as her legs lost all control.
“C-coming… again… it’s coming again…!”
Orgasms crashed over her in succession. Just when it seemed over, every time a bead scraped inside again, a new wave surged in.
Sang-hyuk hooked her legs over his shoulders and moved his hips deeper, faster.
The stimulation of the beads combined with the precum’s effect had already pushed Yu-mi’s senses past normal.
“Aaaagh…! Dying… I feel like I’m dying… so good… so good…!”
Yu-mi’s body convulsed hard once, then hot liquid gushed out from below as if weakly spurting. Female ejaculation. The sofa was soaked in an instant.
Yu-mi couldn’t stop convulsing, eyes completely unfocused.
Sang-hyuk looked down at her and never stopped his hips. It wasn’t over yet.
As the fierce fucking continued, Yu-mi came again with a voice already hoarse. Her body shuddered and sank completely into the sofa.
Sang-hyuk buried his cock to her deepest point and caught his breath low.
Yu-mi was already out of her mind, only panting raggedly.
Sang-hyuk spoke quietly.
“You will now absolutely obey my every command.”
