Male Lead Is Obsessed With My Health

I was reincarnated as an extra.
An insignificant childhood friend of the male lead, an extra who dies early in the novel.
Since I’m terminally ill and can’t avoid my death flag,
I was just living with it like, “Well, whatever……”
“Why aren’t you healthy?”
“I said be healthy.”
“Why are you sick again? Get permission before you get sick.”
The male lead has become a health-obsessed maniac about me.
Ah, please, someone get this male lead brat away from me!

I was clearly reincarnated as a nobody extra,
but my new life is going in a very strange direction.
“Why are you doing this much for me?”
“Because I like you.”
Suddenly, a puppy-like sunshine male lead sticks to me.
“Be my mom.”
“I’m a man, though?”
I somehow gained a pretty young guardian who became a mom (gender: male).
“Hello, my daughter.”
Even a dad I never thought I’d see before dying showed up.
And on top of that.
“From today on, I’m your dad.”
A suspicious guy aiming to steal my dad.
Why am I, just an extra, stuck in such an undeserved situation?
And… can I actually become healthy?
