A young man, around fifteen years old, was walking under the late afternoon sun, at that moment when the light turned golden and soft. The air was cool, still carrying traces of the day's heat, gently warming his skin. With each step, he seemed lost in his thoughts, his gaze drifting into the long shadows of the trees and the gentle breeze whispering through the leaves. Night was slowly approaching, but the sky still held warm hues, like the last breath of summer before the evening arrived. Once at the entrance of his alley, he saw a car speeding toward him. He didn’t have time to react before he was thrown into the air. In those final moments of suffering and his last breath, he died—but...

Just as the game's tension peaks, his laptop glitches and freezes. "Ughh, not again!" Sevi groans, frustrated with his malfunctioning laptop. Suddenly, the screen emits a bright flash, revealing an otherworldly interface that prompts him to select a player. "Wha-- Before Sevi can react, another flash envelops the room. He finds himself in a luxurious medieval setting, dressed as a young duke with a plump figure, silver hair, and purple eyes.

He blinked, but the vision was still there. He saw a beautiful woman fully naked on the edge of the other side of the spring. Her slightly wavy hair with the color of copper cascaded freely down her slim waist. She raised her arms and dived cleanly into the water. Marx waited, but after some time, she did not emerge. Marx chuckled. How could a woman be in a jungle in the middle of nowhere?" He heard a growl from behind him, and before he could react, a big tiger pounced on him. The last thing he remembered was seeing four canines closing in and hearing a loud female voice shouting, "Khalil, stop!" … Discover how Amaya, who grew up in the wild, coped with the pressure and challenges of returning to the civilized world.

--- Kai Vale never expected to wake up in a high-security research facility, let alone one belonging to S.H.I.E.L.D. As he took in his surroundings, his eyes landed on the object of their intense study—a transparent blue cube radiating an otherworldly glow.

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.

"Any who don the title of 'king' or anything of the sort in my presence is nothing more than an ignorant fool. This is my land and I shall be reclaiming it soon. I am Cacophony, the Vampire Empress!" As those words left her lips, every cell in my body reacted. It was unreal—no, it was otherworldly. Her beauty, her power, and her overwhelming arrogance.

Exploring the world’s hidden secrets, forging unexpected bonds, and living alongside the revived empress—it’s exciting. "Even if it's wrong, I think I'm going to enjoy every moment of it."
