Another world

Makoto was sitting at home. Again.
The monitor glowed with an empty document, the cursor blinked like an irritated cricket.
"Damn... what should I write next?" he drawled, staring at the ceiling. "That's it. The muse is dead. I need to go out, get some oxygen. Maybe I'll get inspired."
He pulled on a sweater that had been asking to be washed for a long time, and left the apartment. He walked around the park for about forty minutes - and then, bam, an epiphany!
An idea! A boy, another world, magic, monsters! Brilliant!
Makoto, without waiting for the end of the walk, rushed back.
"He-he... I'm just a monster of a pen. My novella will blow up the ratings! And girls will line up!
Running outside, he joyfully waved his fist at the sky.
"Almost home! All that's left is to cross the road! Green... let's go!"
He confidently stepped forward. And then — the fatal moment.
A truck flies out from the left.
— What?! A SAAAAAAAN TRUCK???
Makoto prepared to say goodbye to life, remembering all of his two subscribers. But...
The truck stopped. The driver pressed the brake. Everything was fine.
Makoto, with an expression of philosophical trauma on his face... wet himself. And passed out.
A classic of the genre.

He woke up on a bed, in a white room.
— Probably, this is white light... am I dead?
— No, — the nurse answered. — You just passed out from shock. Everything is fine.
— Oh... yes? Thank you for worrying... Can I be discharged now?
— Of course. Just... tell me, do you have any relatives? We didn't find a single contact in your phone...
— ...No, — Makoto answered with slight sadness.
Awkward silence. The nurse nodded and left.
An hour later, Makoto was walking home, trying to remember that brilliant idea.
- Hmmm... what was the story?.. Oh, whatever, I'll remember later. I need to sleep.
He collapsed on the bed without even changing and passed out.
---
White light.
Again.
- Now this isn't a hospital anymore...
He found himself in a strange, unfamiliar world. And then - a voice in his head.
> 💬 System: Hello, human. Welcome to another world.
- AAAAAH! WHAT? WHO? WHERE? IS THIS A DREAM? AM I SLEEPING? WAKE UP! WAKE UP!!!
> 💬 System: Calm down. This is another world. There is magic, adventure, and you are all alone. Enjoy.
— ...well, typical. All I need to know is that I have to save the world from demons, huh?
> 💬 System: Ha! No.
You're here because... uh... well... it's a long story. Forget it.
Your name is Marcus Kannet, you're 16, and you've been accepted to the Schwaltzfer Academy of Magic. Welcome.
— What? So... I'm a teenager now?
> 💬 System: Yeah. You're in another guy's body. He's in yours. You can't change back.
— ...at least you don't have pimples.

Skill: "Writer"
> 💬 System: This is your main skill. One of the most powerful... potentially.
— Potentially?! What nonsense?! Why not "Swordsman", "Summoner", or at least "Berserker Chef"?!
> 💬 System: This skill allows you to write a story that will happen in reality. But with restrictions.
Rules:
1. 3 times a day.
2. Nonsense is not accepted.
3. No killing, buffs or hacks.
4. For violation - death. Good luck!

Markus sighed.
- Well, let's see what you can do, my golden ink friend.
SKILL "WRITER" ACTIVATED.
THE STORY BEGINS...
> "A nice gift awaits Markus upon returning home."
Mana: 120/300
- Ha! It worked! What will it be? A girl? Money? A sandwich?
