Obsessed Male Lead Made Me The Main Character

Welcome to <The Adversary of the Evil Dragon>!
I am a guide for travelers who have come into the novel.
You have become 'Tiarozeti Isol'
To return to your original world, you must complete the novel.

"You have to be happy… I will miss you."

Somehow, I fell in love with the male protagonist, Lexion Spero, and ended the story by dying for him, but strangely, when I opened my eyes, I was still in the novel…?

"The new main character is Tiarozeti Isol."
However, this time, not only have I become the main character-

"-Titi, choose me, not this damn fate."
Unlike the previous life, Lexion's obsession for her begins!
