Getting transmigrated inside a novel is not really a bad thing—you know the story, you have the power of the future in your hand, you know all the hidden keys. You might as well end up as the most powerful and omniscient being in that world.That is, if you don’t wake up during the epilogue.And yet I find myself in the body of a fallen priest at the end of the novel, a tragic hero who had his mana circuit broken in the last war, being shunned, drown in debt, and destined to die not long after.Fortunately, I know just the cure.Unfortunately, the cure was in the hand of one of the Demon Lords—you know, the race that my kingdom just wage war with.Would he give me the cure if I asked him politely? There’s no harm in trying, right? I’d die if I didn’t get the cure, anyway.“Sure, but you have to be my bride as the price,” the Demon Lord said....huh? Sir, you know I’m (technically) a priest, right?

Nie AnAn woke up one day and realized that she had transmigrated as the villain’s adoptive sister.

In the novel, the villain conquered left and right, and his always woe-is-me younger sister was always cleaning up after him. The two of them were rightfully the grim reapers in the book.

The very next day after her transmigration, the soft and delicious Nie AnAn passed out from seeing blood.

And so —

The shivering competitors noticed that their nemesis’s sister had turned to a delicious treat — and wanted to protect her;

The original male lead noticed that young Miss Nie, who had been chasing after him this entire time, wouldn’t even give him the time of day anymore — and felt unbalanced;

Young Master Nie was very happy that his parents had two kids back then– she was so GD cute;

A certain cold blooded and violent villain had been going home earlier and earlier, and the way he talked was becoming gentler and gentler.

Villain Brother: AnAn, come over. Let me try some of it.
Nie AnAn: Hold on, gege. It’s not ready yet.
