I Only Tried to Seduce the Villainess Sister Who Was Supposed to Kill Me

I possessed a novel I’d read before I died.

And not just any role—I became a gruesomely killed extra who gets mu*dered by the assassin the villainess big sister sends, after I defend the heroine right in front of her!

While everyone else was busy fawning over the heroine, I was the one obsessed with the villainess sister—her girl-crush aura and, once you get to know her, her surprisingly kind personality… I only ever had eyes for her…!

Well then. I’m done being “the heroine’s sacrificial lamb #1.”

I’ll seduce the villainess big sister and make her my ally!

So I even volunteered to be her foot-wiper and started trailing after her everywhere…

And this sister—she may be wicked as hell to everyone else, but she’s genuinely sweet to her people, you know?

“Elly, your tiny hands are all scraped up! This is something I should be doing!”

“I’ll make you the greatest goddess at the debutante ball, Elly.”

“That bastard tried to hit on you?! How dare he—my one and only friend?!”

Once the villainess sister opened her heart to me, she turned out to be a total softie who’d give her friend absolutely anything.

But then—

“Lady Ellinea, that ability you just used… could it be the dark attribute?”

Theohr, the archduke’s son who saved me in a carriage accident, mistakes my black magic for the same “dark attribute” as his own—

“How do you know about the ability I have?”

And because I read the original story, I let slip that I knew about Crown Prince Lloyd’s hidden power… and I end up catching his attention.

On top of that—

“Lady Ellinea is God’s proxy, bearing both the light attribute and the dark attribute.”

The youngest high priest sees my black-magic healing and suddenly claims he received a revelation—then goes around proclaiming I’m God’s proxy.

Wait, me?!

This healing power isn’t light-attribute magic—it’s just my black magic…!
