You’re Mistaken—I’m Not the Final Boss’s Lover

I possessed a game character.

Since I’d already possessed her, I devoted everything to the protagonist in order to see the true ending... only to be discarded like a used rag.

While I was seething with betrayal, an unexpected person appeared before me.

It was Mayer Knox, the black knight who is this game’s final boss!

"Jun Karentia. I would like you to join my expedition, the Black Knight Corps."

Forced into joining the Black Knight Corps by his refusal-to-take-no-for-an-answer pressure, I ended up there against my will.

Fine, couldn’t the final boss become the protagonist too?

And while I’m at it, I can hit back at the protagonist who abandoned me.

But things did not go as smoothly as I had imagined.

Mayer keeps acting overprotective... and on top of that, strange rumors are spreading!

"Is that her? The vice-captain His Excellency chose?"

"I heard she’s His Excellency’s lover..."

Wait a second! Final boss’s lover? That’s a misunderstanding!
