Tanker Qualities 2. Thud.
The cold texture of the ring floor pressed sharply against Harina's burning cheek. Every muscle in her body screamed in protest, but her mind was strangely clear. And at the center of that clarity was the vivid image of her oppa, Hadojin, who had just overwhelmed her completely.
I lost... completely. More than frustration, a sense of relief washed over her first. His cold gaze looking down at her, laced with a faint hunger for conquest. Recalling how her body had reacted the moment she met those eyes made her face flush hot.
Am I... really a total perv?
Harina tried to get up, but her legs had no strength. That's when Hadojin approached and knelt beside her.
"Can you get up~♥?"
His voice held none of the earlier coldness; it was filled with gentle affection again. The soft tone of her ege-nam oppa. That gap only confused her heart more. She raised her hand to grab his.
Squish. Hard.
Instead of his hand, she grabbed... her oppa's dick.

Looking down at the fallen Harina, I felt a new emotion writhing inside me. I wanted to wreck her completely. I wanted to see that strong gaze crumble because of me, begging, submitting. Sadist. The violence I'd cultivated in prison to protect myself was manifesting in a different form here.
But at the same time, I remembered the novel's plot.
Harina... dies because of her weak durability.
In the original story, Harina becomes the successor to the Fist King, blooming with dazzling talent. Her attacks were faster and sharper than anyone's, but she couldn't withstand a single fatal blow and met a pathetic end. Her weakness was clear: defense, or toughness.
This peculiar tendency she was showing now. The masochistic trait of finding pleasure in pain. It wasn't a flaw—it might be the only key to saving her.
Tanker.
The role that advances while taking hits, enduring enemy attacks with their whole body. Harina's M-tendencies were the perfect talent for becoming a tanker. If she could transmute pain into pleasure, she could endure any training.
I revised my plan. Not just teaching her boxing, but raising her into this world's greatest tanker. To ensure she wouldn't die in the future, forging steel-like toughness that wouldn't break under any attack.
"Can you get up~♥?"
Ah, fuck. I'd let my guard down, and that damn ege-nam voice slipped out again. While I panicked for a second, Harina's hand suddenly gripped my semi-erect dick tight.
Squeeze—
"Gasp..."
Harina was shocked, and so was I. We both blushed furiously as our hands pulled away.
"Ah. Fuck. I thought it was your hand. Don't make it so big."
My excuse only made her beet-red face drop even lower. Her pupils shook violently, and love juices dripped steadily from between her legs.
The mood couldn't get any lewder. Not yet. Harina still needed more tanker training; her maso energy couldn't be released through sex yet.
"Rina."
I gently stroked her cheek. Her shoulders trembled.
"You actually have tremendous talent."
"Wh-what are you talking about? I couldn't even touch you, oppa..."
Harina mumbled with her head down, biting her lower lip to fight off her arousal.
"No. You have the qualities to become the ultimate tanker."
"Tanker?"
"Yeah. There was a legendary boxer named Rocky Marciano. He never lost once. His secret wasn't genius offense. It was steel-like toughness—advancing while taking hits. Enduring every attack until the opponent collapsed from exhaustion, then finishing with one punch. That's a tanker."
I persuaded her with a plausible story. Her eyes began to sparkle little by little. Having overcome her arousal, she looked at me with shining eyes.
"Me... I have tanker qualities?"
"Of course. Normal people avoid pain. But you? You pushed through it and charged harder. Not just anyone can do that. It takes insane mental strength and talent. Feeling good while getting hit? That's proof your body accepts pain as nourishment for growth."
Harina's expression shifted subtly. In place of shame and confusion, faint pride and curiosity sprouted. The thought that her pervy tendencies might actually be special talents.
"So... I'm not weird?"
"Obviously not. You're special. But to bloom that talent fully, you need proper training. Just taking hits doesn't make you stronger. Cumulative damage will drop you eventually."
I looked straight into her eyes.
"You need to learn to slip, block, and absorb impacts. That's how you become a true tanker. I'll teach you. Can you trust me and follow?"
Harina was silent for a long time. She looked down at her hands. Then, resolute, she lifted her head to meet my gaze. No more confusion in her eyes.
"Yeah. I'll do it. I'll learn everything you teach me, oppa. I wanna be the best tanker."
Her voice brimmed with determination. I smiled in satisfaction. Phase one of the plan: success.
"Good. Then get up. One more round. This time, defense training—no attacks."
I helped her stand. She took her stance on the ring far more steadily than before. I set aside the mitts and faced her with bare fists only.
"Alright, I'm attacking now. Just dodge or block. If you think you'll get hit, take a stance to minimize impact."
I started with light jabs. Clumsy at first, but Harina picked up defensive techniques at an astonishing speed. She weaved to slip my fists by a hair, ducked to let attacks slide over her. Unavoidable ones, she absorbed with a high guard.
"Good. Keep your head moving. Watch my eyes, predict the next attack."
My praise made her movements even smoother. She no longer feared pain. Each time my fist grazed past, she seemed to feel a thrilling pleasure. Her eyes sparkled with joy.
"Haa... haa... This is fun. So fucking fun!"
Sweat poured off her, but she grinned. She was enjoying discovering her talent and honing it.
I marveled at her growth while feeling my sadistic urges sated. Tempering her, raising her, turning her into the ultimate weapon only I could wield. Just thinking about it made my crotch heat up.
The intense hour-long session ended. Harina was utterly spent, but her face glowed brighter than ever.
"Oppa... thanks. I had no idea I had talent like this."
"You followed well—that's why. You'll definitely be the best tanker."
I ruffled her hair. She closed her eyes blissfully, no longer shy. She was so adorable, I couldn't help planting a light kiss on her forehead.
"......!"
Harina froze. Her eyes went wide like a rabbit's as she stared at me. Her cheeks burned crimson.
"Th-this... part of training?"
"Nah. Praise for doing good."
I grinned and headed out of the dojo first. Left behind, Harina stood frozen for a while, touching her forehead.
On the walk home, Harina stuck close to my side. She said nothing, but her whole body radiated happiness. She seemed over U Jeong now. Her mind was full of our training—and that kiss.
At home, An Hyeonmi greeted us. Seeing us drenched in sweat, she smiled warmly.
"My son worked hard training his little sis. Good job, Rina too. Go wash up quick. Mom made a yummy breakfast."
An Hyeonmi's praise always lifted my mood. She was fully on my side now. A staunch ally supporting my plans, wishing for my success more than anyone.
While Harina showered, An Hyeonmi approached and whispered.
"Master... last night was the best.♥ I'm so happy being Master's cumdump."
Her eyes held absolute trust and love. I wrapped an arm around her waist.
"Look forward to tonight too, my cumdump."
"Yes, Master.♥"
She pecked my lips and headed to the kitchen. Then the front door opened—Haruna entered, fresh from morning jogs.
"Oh, everyone's up early? Dojin and Rina already trained? Impressive, really."
Haruna's praise made my shoulders lift. This is what family recognition feels like. A warm, fulfilling emotion I'd never known in my orphan past life.
The table held steaming dried pollock soup, rolled omelet, and side dishes. We all sat.
Freshly showered Harina looked even brighter.
"Wow, Mom. This pollock soup hits the spot."
"Tastes better after exercise, right?"
The warm meal began. Then—
Ding-dong.
The doorbell rang. All eyes turned to the entrance. An Hyeonmi stood puzzled.
"Who could it be? This early..."
She checked the intercom—her face stiffened slightly. She glanced at me, then opened the door.
"Oh, Yujeong! Come in!"
At the door stood U Jeong, dolled up even prettier than yesterday, hands full of dessert boxes.

"Hello, ma'am! Good morning, Harina! And... my future boyfriend Dojin oppa!♥"
U Jeong set the boxes on the table and rushed to hug me. The table's mood froze again. Harina dropped her spoon with a clang. Her happy face hardened instantly. An Hyeonmi forced a smile, but her eyes were icy. Only Haruna, oblivious, welcomed her brightly.
"Oh? Yujeong's here. Eat with us."
Harina's pupils spun. Internally, I cheered. Jealousy is the best growth catalyst. Today, Harina would get stronger than yesterday. Outer toughness matters, but inner toughness does too.
