Male Lead Is Obsessed With My Health

I was reincarnated as an extra, the non-existent childhood friend of the male lead, who dies early in the novel.
I can’t even avoid the time limit dead flag.
That’s why I was living like this…
“Why aren’t you healthy?”
“I’m healthy.”
“Why are you sick again? Did I allow you to be sick?”
The male lead became obsessed with my health.
Oh, please, can someone get rid of this guy!

I was definitely reincarnated as an extra with no presence. But my new life is unfolding strangely.
“Why are you doing this for me?”
“Because I like you.”
Suddenly the sunny male lead started sticking to me..
“Mom, do it for me.”
“I’m a man.”
And a handsome guardian who became my mother (gender: male)…
“Hello, daughter!”
Even a dad who was supposed to die appeared before me…
Also..
“From today on, I’m your dad.”
A suspicious human was aiming to become my dad.
Why did I put myself in this undeserved situation as an extra? Can I really become healthy?
