Reincarnated as a Vampire, I'm So Well-Behaved, Big Sister Saintess

Transmigration + gender transformation into a girl + yandere top vs. tsundere bottom + pure love + turning the tables and teasing her back.

In her previous life, she was a male office worker who spent his evenings reading web novels and arguing with internet trolls. One day, she got so worked up she couldn't catch her breath and actually died of anger.

When she awoke, she discovered she had been reborn into a Western fantasy novel as a silver-haired, red-eyed vampire princess.

The original ending: The Saintess runs a sword through her heart.

To stay alive, she decides to strike first. She'll infiltrate the church and kidnap the Saintess!

Before the Saintess has a chance to grow stronger, she'll mold her into an ally.

The plan is perfect, and she carries it out without hesitation. That very night, she wraps an arm around the Saintess's waist and delivers a fierce threat, all in one smooth move.

Instead, the Saintess pins her to the bed with one hand.

“You said you were going to kidnap me?” Solanya smiles sweetly, but can't quite hide the madness in her eyes. “But from where I'm standing, you're the one who came looking to be caught~”

Lilith: Wait, I'm supposed to be the kidnapper!

I thought this was supposed to be a battle between good and evil. How did it turn into a showdown in bed?!

Solanya: “Don't even think about running away~ You can't escape.”

Lilith: “Haha... Big Sister Saintess, I'm actually super well-behaved. Could you let me go back and report in first?!”

Solanya only smiles, pulling her even closer.

Wait... The Saintess wasn't supposed to be this strong at this point in the original story. What went wrong?
