Not the Heroine nor the Villainess, Just an Ordinary Mob character

Elle is just an ordinary mob character. Her name might have been mentioned in the story but she never appeared even once. So, there's really nothing for her to worry unlike in those stories where the reincarnated MCs would go overly worried about their future. All she has to take care is her own body and recuperate.

So...

Why is the final boss taking care of her and acting as her personal physician?

"Don't forget to take your medicine along with the red pill."

Looking at the bloody red pill in her palm, she couldn't help but nervously gulp.

"This is not blood right..?"

The man only smiled more gently at her question, so she quickly look at another man who had been standing aside them this whole time. He was looking at her worriedly and kept nodding at the physician's words.

Male lead! Why are you agreeing with the final boss!?
