Chapter 47: Chapter 47 : Explanation

Eiden remained locked in the kiss with Sasha, neither of them moving nor making a sound. Their eyes stayed open, staring at each other as the weight of what just happened began to sink in. The moment was oddly quiet, intimate in a way that made the air feel thick.

But just as tension began to mount, a voice interrupted the moment. "Eiden? Sasha? Hello?" It was his mom. Eiden jolted upright, breaking the kiss as if he had been electrocuted. His eyes darted to Sasha, who looked just as stunned but immediately nodded when he gestured her to stay silent.

"I-I got the cockroach, I’m gonna throw it!" Eiden shouted toward the door, his voice slightly panicked. "You can go, Mom!"

"Umm... okay then," his mother replied after a short pause, her footsteps fading as she walked away. Once the coast was clear, Eiden turned back to Sasha. She was still seated, dazed, her fingers trembling slightly on her lap. Eiden exhaled, mentally forcing himself to focus.

"I need to show you something," he said, his tone shifting to something serious. "Can you look at it?" She nodded slowly. "I’m sorry," Eiden muttered, eyes drifting to the translucent interface in front of him. The system was still processing loading at 96%... 97%...

"I’m sorry for lying," he continued, glancing at her. "About not knowing why I suddenly grew overnight. I knew. I just... didn’t know how to explain it." Sasha’s lips parted to say something, but Eiden raised a hand quickly.

"Wait wai-wai-wait! Just... just listen first, okay?"

She closed her mouth, nodded again, though clearly confused. "I’ll show you some... medical reports," he said as the loading bar finally reached 100%.

"Medical reports?" Sasha echoed, brows furrowed. Eiden winced but pressed on. "Please. Just take out your phone and search something." The system’s voice chimed in his mind.

[System-chan: Tell her to search ’Meriocolosiosis’.]

"Search for ’Meriocolosiosis’," Eiden said out loud. Sasha hesitated but took out her phone and typed it in. The search results immediately flooded with documents, research papers, and medical blogs. She clicked the first one.

It was a detailed report on a disease no, a condition l called Meriocolosiosis, also coded in clinical research as ROP-G567. The disease, according to various reports, was a dormant genetic phenomenon that awakened during early adulthood typically around the late teens or early twenties.

Its effects were bizarre: rapid height increase, enhancement of strength, speed, intelligence, even changes in voice and facial structure. In some cases, the reports said, the individual’s entire physical appearance matured overnight. There were no negative health impacts; in fact, the disease made the host unnaturally durable and adaptive, as though it was trying to keep the host alive for as long as possible. According to the documents, it had a human-like lifespan and seemed symbiotic in nature.

Only four cases were ever documented. The first case was in 1984, involving a man named Calies Vincent. The last was in 2010 Duker Darins.

Sasha’s fingers trembled slightly as she scrolled. She didn’t understand everything in the medical jargon, but even with her limited biology knowledge, she knew this disease sounded... absurd. Too convenient. Too sci-fi.

Still, she kept reading. The reports were published by what appeared to be real medical institutions. Seals from known hospitals were stamped. Names of famous doctors, researchers even one she had heard of from a TV documentarg were listed as contributors.

And then she stumbled upon a documentary video link. She tapped on it. There on screen was a well-known figure in the global medical community, calmly explaining the condition. Charts and X-rays appeared. He even referenced a potential for the disease’s unique blood composition to help treat lung cancer, rare autoimmune disorders, and degenerative diseases.

Her eyes widened. It wasn’t just one article. It wasn’t just one site. Multiple sources websites, medical review boards, forums, even TED Talk snippets were all citing the same rare condition.

She looked up at Eiden, her face pale. "You didn’t want to go to a doctor because... of this?" Eiden nodded. "I don’t know exactly what’s in those documents either. I can’t even view the full report like you can. But the system... it gave me glimpses. Just enough to know this was the best way."

Inside, Eiden was sweating. System-chan really cooked up something terrifying, he thought. It even created full-blown documentaries with real-looking doctors. This thing could frame someone for murder if I wanted. That’s way too much power for one person to have.

Sasha remained silent, but her expression was conflicted. "When... When did you find out about this?" she finally asked. Eiden looked at her calmly. "A week before your birthday." Her shoulders slumped slightly.

"Do Mr. and Mrs. Mores know about this?" she asked after a pause. Eiden shook his head. "No. Mom and Dad don’t know either. You’re the only one who does. Besides me."

Sasha stood up slowly. Walked to the door. Without a word, she opened it and left. Eiden just sat there, stunned. Watching her back as it vanished down the hallway.

He didn’t go after her. Instead, he slumped onto the couch, buried his face in a cushion, and screamed internally. What the hellllll!! I just kissed her! My first kiss! Was with Sasha!!

What the actual hell!!! His entire body squirmed in mortification. He groaned and rolled over like a dying fish on land.

If she wasn’t Sasha, I’d 100% be in jail for sexual assault right now. AHHHHHHHHHHHHHH!!!

Trying to distract himself, he grabbed his phone and pulled up what Sasha had been reading. The system’s files had loaded onto his interface now, letting him examine the documents without suspicion.

He began scrolling, eyes wide, scanning everything. Every report had detailed formatting, proper terminology, and expertly crafted research language. The more he read, the more impressed and disturbed he became.

"This is way too convincing..." he whispered. "If I didn’t know the truth, even I would believe this." After nearly five minutes of reading, he shook his head and stood up, heading downstairs.

Sasha was already seated at the dining table, quietly eating breakfast. Her face was calm, unreadable. Eiden sat beside her without saying anything. He ate his meal silently.

Once finished, the two stepped out of the house and began walking toward college. The atmosphere between them was heavy with unspoken words. Eiden glanced sideways at her multiple times. Her eyes were fixed ahead.

Finally, he nudged her arm gently. She looked at him, puzzled. Eiden grinned. "So... how was the kiss?" Her eyes shot open in shock. Her cheeks flushed red almost instantly. Without hesitation, she slammed her fist into his gut.

"Stupid!!"

She spun on her heel and sprinted down the sidewalk, leaving Eiden bent over in pain, groaning. He clutched his stomach, wheezing. "Ow... okay... not how I imagined that going..." He watched her retreating figure disappearing in the distance and frowned.

I just wanted to ease the tension a bit so things wouldn’t feel so awkward after the kiss... I thought Sasha would laugh it off or play along like usual, make it seem like no big deal...

But that reaction? Eiden remained frozen in place, blinking.

"...What the hell is going on with her?"
