"Yeah, yes, just keep going, I'm almost-" I heard a boy scream. Who the fuck moans loudly like that? I doubt the dick is that good for him to scream like that. I make my way towards the particular door, navigating through several people, some passed out drunk. Tipsy and nosy, I forcefully open the door to see Rex, the guy I imagined as a nerd, serious and asocial, giving handjob to Jess, my supposed friend. Of course it's not a big deal, we weren't dating. The problem was that I had a crush on him and we just kissed a few mins ago. Jess turned towards me, his face twisted in pleasure as he came. A cruel smirk then appeared on his face as we maintained eye contact. I left. That was the last time I saw Rex. A year later, we ended up in the same university, same Faculty, same street, same apartment, next door neighbour. -------------- "I bet you have wet dreams about me." he smirks, taking a sip of his drink making that 'ahh' sound annoying people do after taking a gulp of their drink. "Shut up Rex, you're not sexy or attractive enough for me to have wet dreams. So shut up and take your stupid drink inside with you." I said, going inside my room and slamming the door shut. I lied, Rex was attractive and sexy enough for me. AUTHOR'S NOTE: Their story started a little from A CHANCE AT LOVE but can be read as a stand alone. I'll explain their backstory here but there's no harm in reading A Chance at Love right? Enjoy!

Synopsis: Rise from Zero to Hero In a world forever changed by the arrival of the mysterious Red Sun, 99% of humanity awakened supernatural abilities. Cities flourished with newfound powers, and heroes emerged to protect society. But with great power came chaos. Portals opened, unleashing monstrous creatures and demonic invaders, plunging the world into a war for survival. The Awaken, an elite group of warriors, rose to defend humanity, ranked by their strength and armed with advanced sci-fi weapons. They became the last hope against the lurking threats. In the remote village of Ikweghwu, a boy named Eli Rume was born with one of the weakest abilities—a simple light glow. Mocked by his peers and seen as a failure, Eli had no place in a world ruled by strength. But when his village is massacred, and his family is taken from him, Eli embarks on a desperate journey for survival. Guided by the legendary warrior Kazien, and trained by the mysterious Old Man Joseph, Eli pushes past his limits, determined to join the Awaken and find a cure for his dying mother. With only two months to prepare for the brutal Awaken Entrance Exam, he must prove that even the weakest can rise. As Eli steps into the battlefield of the strong, he soon realizes that his so-called "weak" power holds a hidden potential—one that could change the fate of humanity itself. From Zero to Hero—the battle begins.

"Fortune favors the bold," they said. Perhaps he was a coward. Even if Kian screamed at the top of his lungs that the universe hated him, no one would believe it. After a life of pure disappointments and tragedies, he was convinced that he wasn't blessed with an ounce of luck. He worked harder than anyone, analyzed further than anyone. Yet, fate refused to acknowledge it, handing the fruits of his labor to another. But he didn't give up. "As long as I'm alive, there's hope," he always told himself. Then he died. At that point, he wasn’t even surprised when a truck with failed brakes accidentally veered straight toward him. What surprised him was the fact that death wasn't the end. When he opened his eyes, he found himself kneeling before a goddess searching for a hero. Kian, clearly unfit for the role, was discarded and thrown into an unfamiliar world—a place that reeked of death. A world that had long since forsaken by gods. He had no divine blessings, no weapons, no cheats, no overpowered skills, and most of all, no knowledge of this strange world. He had endured misfortune for as long as he could remember, believing that the higher power above—whatever they were—would see his perseverance and reward him in the end. But after discovering that even the divine had abandoned him, he made a decision. He would use everything he had to survive. And one day, he would give this world that had forsaken him what it deserved.

I don’t remember being born. None of us do. We wake up at twenty, fully grown, with knowledge implanted in our minds, a communicator fused to our wrist, and a role already assigned. We don’t have childhoods. We have purpose. Or so they tell us. I was a Sparta operative, one of the enforcers of order in this world built from the ashes of war. The hard-fought war between species. A war long forgotten. My job was simple: track down illegal activity, eliminate threats, and keep the system stable. Stability, they said, was everything. But that illusion shattered the day I found him. A Zen Zero Clone. The original prototype. I understood one thing. Maybe everything we knew was not the truth. Maybe there was something which escaped our understanding…… The ones who lived in the Outer Worlds, where the radiation should have killed them, where the Council said no life could exist. The ones who had real children, not just another iteration of themselves, but something new. Something free. Now, I’m running. Chased by the very system I once protected. Hunted by the ones who erased my past and shaped my future. I’ve seen the truth, and they know it.

[Finally… after a looooong time, I’m activated.] Alex’s grip tightened on his greatsword. “Who—or what—are you?” The light flickered, shifting like a sentient mist. [A warrior, clad in crimson steel. Strong, unwavering, and… oh, now this is interesting.] “I asked you a question,” Alex said, his voice firm. The presence circled him, its tone playful yet ancient. [I am many things, Red Knight. A guide. A weapon. A remnant of the past. But above all… I am your new companion.] Before Alex could react, the light surged forward, sinking into his armor. A rush of energy flooded his body, his very bones vibrating with a strange resonance. He staggered slightly as the voice resounded within his mind. [Let’s see what you’re made of, Alex Theodorix. The adventure is just beginning.]

O mundo que um dia floresceu agora é apenas um fragmento do que já foi. Ruínas e colônias improvisadas substituíram cidades e impérios, enquanto os vestígios dos Grandes Antigos espalham terrores invisíveis pelo que restou da civilização. Velyn nasceu nesse cenário brutal, em meio à luta diária pela sobrevivência. Filho de uma mulher marcada pela doença causada pela Essência, ele cresceu com um único propósito: encontrar uma forma de salvá-la. Mas, mesmo após passar pelo ritual de passagem, sua própria Essência parecia inútil—um fardo em vez de uma bênção. Aos 16 anos, diante do peso da realidade e da necessidade de dinheiro para tratar sua mãe, ele aceita participar do Teste dos Portadores, uma provação mortal onde os escolhidos são lançados em dimensões desconhecidas, obrigados a lutar por suas vidas.
