The 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!
