The Extra's Advent: My Villainess Fiancée is a Yandere

[A/N: No smut. Moderate pacing, with a slight lean toward fast pacing to keep the story sharp and avoid dragging. Romance is secondary]

__

I transmigrated into a slow-paced action romance fantasy novel.

You know the type. A naïve, righteous protagonist with a growing harem, invasive creatures to slaughter, a God to kill, and a guaranteed happy ending.

And then there was the Mob villain.

The jealous, exiled half-brother who goes full psycho, challenges the protagonist… and gets killed by his own fiancée.

Yeah. That villain was me, Caelir Vayne.

But everything changed when I awakened SSS class and three op skills.

Cloning. Copy. Fusion.

“…Wait. Isn’t this a little too overpowered?”

But something’s wrong. Why isn’t the plot following the story? Why are events spiraling out of control?

And worst of all…

Why is my fiancée, the girl who killed me in the original story, now staring at me like I’m the only thing that exists?

Hold on. They have a word for this kind of behavior.

“…Don’t tell me... she’s a yandere?”

I recommend reading the free chapters first before deciding whether to continue or leave the novel. Trust the process. The story is planned, and the payoff is worth it.
