The Case When I Attempted To Break The Heroine's Chastity But It Seems To Have an Opposite Effect - 1- Awakening in the Wrong Body

“What the hell?”

The moment I opened my eyes, I was greeted by an unfamiliar place. The classroom was eerily quiet, with sunlight streaming through the windows and dust particles floating lazily in the air. My head throbbed as if I’d been hit by a truck. When I tried to move, my body felt… strange. Everything about it was wrong—too light, too flexible, and undeniably not mine.

“Wait, whose body is this? And this isn’t my room.” I muttered under my breath, sitting up from the desk where I’d apparently been passed out. My voice was deeper, smoother, almost unnervingly attractive.

My gaze caught my reflection in the glass window. Staring back at me was a guy I’d never seen before—no, wait. I had seen him. That perfectly tousled black hair, the sharp jawline, the piercing eyes… This was Ishibara Kaito, the womanizing antagonist from Breaking One’s Heart, the NTR game I’d been playing last night. The realization hit me like a truck.

“You’ve got to be kidding me,” I groaned, leaning back in my seat. “I… I’m Ishibara Kaito?”

What I’m witnessing is unbelievable. Is this real or just a dream? That I’m in the body of a character from a game I played last night. But why Kaito, out of all the characters?

And Kaito wasn’t just any ordinary character; he was the character who stole and broke women, shattering relationships like it was a sport. In the game, he was notorious for seducing innocent girls and dragging them into his twisted world. I shuddered, remembering the cutscenes of his conquests, his smirks, and his manipulative charm. And now, I was in his shoes. Literally.

“I still can’t believe this is real.” I said, touching my face to confirm it was actually mine—or rather, his. My hands brushed against high cheekbones and smooth skin. My body felt lean and powerful, like someone who spent just enough time at the gym to look good but not too much to appear bulky.

As disturbing as it was, I couldn’t deny one thing: Ishibara Kaito was stupidly handsome. The kind of guy who could walk into any room and turn heads. But that didn’t make this situation any less bizarre.

I wracked my brain, trying to remember how this could have happened. The last thing I recalled was playing the game late at night, trying to finish Kaito’s route and his conquest on someone. I almost achieve the ending. There was this one crucial moment… with Kishimoto Miyuki, the main heroine… and then I blacked out.

“I should’ve eaten a more healthy food. I guess “you are what you eat” quote is somehow true.”

A chill ran down my spine. I glanced at my reflection again, my lips curling into an involuntary smirk that felt so unlike me but so much like him.

“What should I do now?” I murmured. The obvious answer was to find a way out of this world. But how?

“The game’s ending… maybe that held the key.” I murmur. If I could see it through to the end, maybe I’d find my way back in my own world.

The problem was, I hadn’t finished the game. I didn’t know what happened next. Bu there was only one path forward for this mission: to play my role. And that meant stealing Miyuki from Haruto. A twisted sense of curiosity bubbled up in me. What would it feel like to see her fall? To break her?

I shook my head, trying to dispel the intrusive thoughts.

“Get it together. This isn’t you,” I told myself. But deep down, I knew the temptation was there. To see her shattered expression, to understand the allure of Kaito’s actions… Maybe that would lead me to the answers I needed.

Just as I was lost in my thoughts, the door to the classroom slid open with a loud clatter. My heart skipped a beat, and I turned to see none other than a familiar person. It was Kishimoto Miyuki herself standing in the doorway.

She looked exactly as she did in the game: radiant, almost angelic, with her school uniform fitting her perfectly. Her short blonde hair glowed in the sunlight, and her big eyes fixed on me. For a moment, I was mesmerized.

Kishimoto Miyuki: she was the quintessential heroine: beautiful, pure, and kind-hearted. Her short blonde hair framed her face perfectly, and her big, innocent eyes made her seem almost otherworldly. She was the type of girl you’d protect at all costs. In the game, she was fated to end up with the protagonist, Matsubara Haruto. But Kaito… he was meant to ruin her.

She looks at where I was sitting, then she frowned.

“Ishibara Kaito, so this is where you’ve been.” she said, her voice tinged with annoyance.

“What are you doing here? The teacher’s looking for you. If you don’t show up soon, you’re going to get in trouble.” Her tone was cold, almost dismissive. She didn’t even wait for me to respond before crossing her arms and glaring at me.

“Uh, sorry. I think I overslept haha.” I stammered, caught off guard.

Her frown deepened. “Is that why you’re always late in class?” she said, her voice sharp.

I couldn’t help but notice how beautiful she looked even when she was annoyed. Her lips were set in a pout, and her brows furrowed slightly. She seemed so real, so alive.

As she turned to leave, I felt a dark thought creep into my mind.

“I wonder what kind of reaction she makes when I break her” I whispered to myself, a sinister smile forming on my skin.

Miyuki glanced back at me one last time, her eyes filled with disdain. “Well, what are you waiting for? Hurry up and go.” she said before disappearing down the hallway.

I took a deep breath, collecting my thoughts. If I was going to do this, I needed to plan carefully. The game’s protagonist would be my first target. If I could gather information about him and his relationship with Miyuki, it would give me the leverage I needed to execute my plan.

With renewed determination and a goal in mind, I stood up and made my way out of the classroom. The hallway was bustling with students, but I barely paid them any attention. My mind was focused on one thing: breaking Kishimoto Miyuki.

The sun has cast an afternoon glow in its light, making a rather near orange light that shines in the hallway. But barely have exposed at the sun’s golden glow as the hall was as empty as an unused can. Well, except for me, as I was making my way to where the classes supposedly start, which is in the science room.

As I walk toward to where the room is, I spotted a rather familiar figure in front. It was actually Matsubara Haruto, the protagonist of the game.

What a surprising encounter I thought.

He looks exactly as I remembered in the game: short black hair, a slightly hunched posture, and an awkward demeanor that screamed “everyman.” He looked so painfully ordinary that it was almost laughable. How was someone like him supposed to win over a girl like Miyuki?

Haruto was walking in the hallway, fumbling with a notebook and looking around nervously. He seemed completely oblivious to my presence. For a moment, I felt a pang of guilt. He was just a kid, caught up in a story he didn’t even realize he was part of. But then I reminded myself: this was all for the sake of going back to my old world.

As I passed by him, I gave him a brief nod. “Yo, Matsubara,” I said casually.

He jumped, startled by my sudden acknowledgment. “O-oh, hi, Ishibara,” he stammered, his voice barely above a whisper.

“Going to where the class is huh?”

“Yeah. I went to get my notebook. I forgot to bring it along with my book. I hope we aren’t late.”

“You shouldn’t worry about being late. In fact, Kishimoto-san have woke me up during my beauty slumber, so I guess there’s still time?”

The science room was just ahead, but I slowed my pace, glancing back at Haruto. There was something almost pathetic about him. Then again, he had one major advantage in this world—his childhood connection with Miyuki.

My suspicions were confirmed when I caught up to Haruto and casually asked, “Speaking of which… You and Kishimoto… you’re pretty close, huh?”

Haruto scratched the back of his head, looking embarrassed. “Yeah, I guess you could say that. We’ve known each other forever. She’s like a sister to me,” he admitted.

“A sister, huh?” I repeated, pretending to be thoughtful. “So… nothing more than that?”

His face turned red, and he waved his hands defensively. “No, no, it’s not like that! Miyuki… she doesn’t see me that way.”

They were childhood friends, obviously. I thought, the words forming clearly in my mind. That’s why she’s so close to him. She trusts him, sees him as a constant in her life. But… Judging from what he said, he doesn’t see him as a man. My lips curved into a knowing smirk. If what he said is true, then there might be a chance.

I almost laughed at how easy it was to get him to spill. So, they hadn’t crossed that line yet. Perfect. That meant there was still an opening for me.

“You’re a lucky guy, having someone like her so close.” I said, slapping him on the back in what I hoped was a friendly gesture. He gave me a sheepish smile, clearly unsure how to respond.

By the time we reached the science room, I had already formulated my next move. If I wanted to get to Miyuki, I needed to stay close to Haruto. Befriend him, earn his trust, and use him as a bridge to reach her.

As we entered the classroom, my eyes immediately sought her out. Miyuki was seated near the window, her golden hair catching the afternoon light. She glanced up, her expression darkening the moment she saw me. Her lips pressed into a thin line, and I could practically feel the disdain radiating off her.

“She really doesn’t like me. I wonder why.” I thought, amused by her reaction.

Haruto, oblivious as ever, walked over to her desk. The moment he did, her entire demeanor shifted. Her frown disappeared, replaced by a warm smile. She greeted him cheerfully, her voice soft and affectionate.

I watched the scene unfold, my mind racing. Her feelings for him weren’t romantic—not yet. But her warmth toward him was genuine. If I played my cards right, I could exploit that trust, twist it, and make her look at me the same way.

“This is going to be fun.” I thought, a wicked grin spreading across my face as I took my seat.
