"Hey, Adam. How are you?"
Adam turned the moment he heard the voice. He was around seventeen years old, with short black hair and dark eyes. His build was well-proportioned, standing nearly 180 cm tall, with a handsome face and clear, pale skin. He instantly recognized the voice—it was his friend Rakan.
Rakan was about the same age, with brown hair, hazel-brown eyes, slightly tanned skin, and an average, natural build.
"Hey, Rakan," Adam said with a faint smile.
"Are you ready to go?"
"Yeah," Rakan replied enthusiastically.
"Let's head to the café."
They walked together through the busy streets, surrounded by the noise of the modern city. Everything felt normal… until something strange happened.
Adam suddenly stopped.
A glowing message appeared before his eyes—blue intertwined with gold—floating silently in the air, as if it belonged to a different world entirely.
[ Welcome to the Tower of Infinite Worlds ]
[ Please select a difficulty level to begin ]
[ Easy – Beginner – Intermediate – Hard – Legendary ]
"Rakan… do you see this?" Adam asked quietly.
He pointed at the floating message.
Rakan frowned.
"See what? What are you pointing at?"
"There's a message," Adam said, swallowing hard.
"A floating message right in front of me."
Rakan burst out laughing.
"What? Did studying too much finally break your mind?"
He laughed again. "Should I take you to a doctor? I knew you were crazy, but not this crazy!"
He patted Adam on the shoulder.
"Relax. You're probably just exhausted. Let's go rest, you'll feel better."
Adam hesitated… then nodded.
"...You might be right."
But the moment he unconsciously waved his hand—
Another message appeared.
[ You have selected: Legendary Difficulty ]
[ Transfer will begin in 5 seconds ]
Adam's eyes widened.
Then the countdown began.
5… 4… 3…
And deep inside, he knew—
His life was about to change forever
