Not the Hero, Just a Background Character — Loved by the Villainess

I reincarnated as a background character. You know, the ones who disappear after a few scenes, who nobody notices, whose existence you forget. But this is my second life. I know it won’t be easy. The journey will be hard. But this time, I will break the fourth wall of this story. I will change my life and the world that tried to force me into the shadows. I will protect my love at any cost. For her, I can go against heroes, side characters, or anyone who stands in my way. I will not become a hero. I will not become a side character. Because I am the background character the one everyone overlooks.
