I was reincarnated as an extra.
The male lead’s forgettable childhood friend, an extra who dies early in the novel.

Since I’m terminally ill, I couldn’t even avoid the death flag, so I was just trying to live with it…

But then…

“Why aren’t you healthy?”
“I told you to be healthy.”
“Why are you sick again? Get permission before getting sick.”

The male lead turned into a health-obsessed maniac.

Ah, someone please get this guy out of my face!
