Not the heroine, but an NPC...
About
"...What? Where am I?"
An unfamiliar bed, a lavish room, and a face in the mirror I've never seen before.
After a moment of silence, I realized.
Ah, I'm screwed. I've been reincarnated. And into a dating sim, no less.
Oath of Holy Light—a classic fantasy romance simulation about the love between a Saintess and two male leads, and the fate of the world.
The man representing the Arden Kingdom in the west, Cassian Edil. A classic handsome knight commander with a perfect chivalrous spirit.
The man representing the Belcar Empire in the east, Cedric Valter. A cold-headed imperial commander-in-chief with a chillingly handsome face.
They are the representatives of two hostile continents and the capture targets of this game.
And there was a separate protagonist who would receive their love and save the world.
The Saintess, Serina Lumiere.
With her beautiful appearance and powerful divine strength, the story of this world was definitely supposed to revolve around her.
Then what about me?
...Could I be the heroine?
No, there's no way. I had no special abilities, no high status, and no protagonist armor.
I was just one of the many NPCs that existed in the original story.
But wait. Was there a development like this in the original?
