I Reincarnated as the Villainess Princess, but the Hidden Character Isn't Hidden: In a World Where Light Shines, With You

"Don’t worry. Even if you’re about to die, I’ll kill you before that happens."
The “assassin” smiled warmly at me as he said those words—

Ever since I became the 5-year-old villainess princess Lucienne in an otome game world, I’ve endured endless violence from the queens and constant hunger.

One day, I met him—Lefèvre, a hidden capture target.
He treated my wounds with medicinal herbs and tucked me into bed, brought me water and biscuits when I couldn’t move.

In the warmth I felt for the very first time in my life, I made my decision:
"If it’s by you, big brother, I don’t mind being killed."

A meeting between two lonely souls—one not in the original scenario—sets out to change the game’s very foundations!
A newly told fantasy of an innocent princess and a cunning assassin, bound by an age gap and an obsessive love!
