I'm so speechless, I don't even know what to say. Honestly, I wish this situation was a hidden camera prank. I wish someone would jump out and say 'Surprise!' with a cake, but seeing as the things flying outside the window are gargoyles and not pigeons, I guess I should give up on that hope.

It was clearly an ordinary commute home. I was waiting for the green light at a crosswalk.

But when I came to my senses, the sky was sulfur yellow, the air smelled like something was burning, and guys with horns, dressed in suits, were surrounding me and clapping. I witnessed all that chaos with my own two eyes.

THEY SAID "We've brought the best childcare provider in the human world!"

They brought me. Are they crazy? They kidnapped me and said they brought me.
Excuse me, I need to go home? I asked, and they shoved some parchment at me, telling me to sign it. They said it's a contract in the demon world. If I don't sign, I can't go back to the human world.

So I did. I did it while crying. I stamped my fingerprint with tears streaming down my face. They didn't even have ink, so they told me to use my own blood. Savages.

Turns out, this is the demon world. And the kids I'm supposed to look after are the children of the demon upper class.
They've given them grand titles, but in reality, they're just strong, disobedient brats.

Tutor?Ran away.
Military Officer?Cried.
Direct Instructor to the Demon King?Resigned after three days.
(The fact that there were tear stains on the resignation letter... is not a secret-)

So, since they couldn't handle it, they kidnapped me, claiming they'd introduce the human kindergarten system. 'The teacher has zero complaints and is ranked #1 in parent satisfaction!' they said!
No, that's for human kids. You're telling me the kids here gnaw on castle walls because their teeth itch, and they carve twelve-ton boulders into heart shapes because they want praise?

Is this parenting? This is animal husbandry.

Right now, I have a year's worth of academic schedule in front of me. I don't know why I have to make it, but they said they won't give me food if I don't, so I'm making it. One line at a time, suppressing my urge to cry.

202X. XX. XX.Sigh. I miss mom.
