"Ugh… another boring day."

Rei slouched in his chair, lazily tapping his pen against the desk as the math teacher droned on about formulas he couldn't care less about. The classroom buzzed with low murmurs, the occasional rustle of paper, and the rhythmic ticking of the clock, each second dragging him closer to freedom.

Outside, the world seemed far more alive. The sky was a perfect blue, students in the courtyard laughed and chatted, and life went on in the most mundane way possible.

Rei sighed, sneaking a glance at his phone under the desk. No notifications. No texts. Just another ordinary school day.

Man… I wish something exciting would happen.

And then—

[Ding!]

> [World System Activated.]

[Assigning Classes…]

A massive blue screen materialized before his eyes.

"What the hell?!"

Around him, students gasped in shock as similar translucent windows popped into existence in front of each of them. The teacher, mid-lecture, dropped his chalk with a clatter. The classroom erupted into chaos.

> [Class Selection: Choose Your Path!]

1. Swordsman – "Master of the blade, swift and deadly."

2. Mage – "Harness the elements, wield devastating spells."

3. Assassin – "Strike from the shadows, eliminate your foes."

4. Archer – "A sniper from the distance, precise and lethal."

Rei's heart pounded. His fingers twitched as he reached forward.

"A system? This is just like a game—!"

But before he could choose—

[ERROR! ERROR!]

> [Random Class Assigned: Fisherman.]

…

A long silence.

Rei blinked. "H-Huh?"

Out of all the cool options—he got Fisherman?!

Then—

> [First Trial Initiated: Survive at Sea for 4 Days.]

His chair vanished. The classroom disappeared.

One moment, he was surrounded by desks, books, and panicking students—

The next—

He was falling.

—SPLASH!—

Cold, salty water slammed into him like a brick wall. His lungs seized up from the shock as he flailed wildly, his arms reaching for something—anything—to hold onto. His vision blurred, the ocean swallowing him whole.

He kicked desperately, his instincts taking over, and managed to break the surface, gasping for breath.

"W-What the hell?! Where am I?!"

Gone was the school. Gone was the classroom.

All that remained was the endless ocean stretching as far as the eye could see.

A small wooden boat drifted nearby, bobbing gently on the waves. He kicked furiously toward it, barely managing to haul himself aboard. He collapsed onto the planks, coughing up seawater, chest heaving.

Then—

> [Survival Trial: Day 1]

[Objective: Survive for 4 days.]

[Failure Condition: Death.]

Rei lay there, drenched, staring blankly at the glowing text floating before him.

"...I'm so screwed."
