On the battlefield, where I was struggling miserably as a young mage soldier, the memories of my past life suddenly returned.
And with them, the realization that this world is actually the setting of the novel .

Of all things… why did I have to transmigrate into a war novel that ends with a mass extinction in the apocalypse?!

To avoid that horrifying ending, I must stick closely to the hero, Leviathan Jebert, and keep a close eye on him so he doesn’t die.

“Sir, do you happen to need a youngest child in your household?”

After countless twists and turns, I finally managed to become the youngest child of the Jebert Duchy.
But the problems are…

I’m a mage—something Leviathan absolutely despises

I’m a deserter who fled the battlefield

And due to a misunderstanding, I even had to change my gender

If they find out, I’ll be kicked out immediately, so I have to be extremely careful…

But this family won’t leave me alone for even a moment.
I’m already busy enough trying to find a way to protect Leviathan…

But first, strawberry cake… Right, delicious!
