I’m a Villainess, Can I Die?

My sister passed away sick, so I don’t want to live anymore.
With that, I chose death, but did I become a villain in a novel?!

Faced with such a sad ending, I thought I could end this troubled life with my own hands…
But why are they still trying to save me?
“Don’t deprive me of your status, Selina.”
“Can you still be greedy?”
My life is getting better and better, and the day of my death is coming. What do I have to do?
