The 17th Princess Just Wants to Live

I found myself in the role of a supporting character who helped the heroine.

It was a brutal political romance fantasy where siblings killed each other over the throne, and I was the younger sister helping the protagonist.

In this second life, I planned to live easily by sticking close to the heroine…

What on earth happened?

And male lead, why are you here?
