Harry Potter: Theodore's Care System

It's finished! I hope you'll give it a good rating.

"You're too skinny. Eat more."

On my first day as a nobody in Slytherin after transmigrating, I got bound to the "Rare Magical Creature Caretaker System."

The System said my charge was Theodore Nott, a background character who doesn't even get a line in the original story, a withdrawn snake who has turned himself into a cactus.

I thought, how hard could it be to take care of someone? Just feed him, right?

But then...

He goes three days without eating, two days without drinking, and five days without sleeping.

He puts down roots and sprouts in the library, then pretends to be a houseplant in the common room.

His only social interaction is: "...Mm."

The System falls apart every day:

"Host! He skipped breakfast again!"

"Host! He's about to die of thirst!"

"Host! He's getting moldy in the library!"

Fine, I'll take care of him.

So I start to...

Bring him pumpkin pasties every day.

Sit with him in the library every day, staring into space.

Stay up with him every night, looking at the moon whenever he can't sleep.

I thought I was just completing missions.

Then one day, the System suddenly displays a notification:

[Warning: Host has been reverse-tamed]

Me: ???

Wait, I'm the one taking care of him, so how did he end up taking care of me?

Even more frightening, the Slytherin who never smiles looks at me as if...

As if there's something different in his eyes?

"Why are you kind to me?"

"Because you deserve it."

This is a story about two dorks feeding each other, keeping each other company, and bringing warmth to each other's lives.

The System says: You two are the hardest class I've ever had to look after.
