Seria, a social outcast, has changed.
Seria Stern, the wicked woman who made everyone tremble with fear, was now calm.

In fact, she wasn’t just changed, she was a completely different person.

The moment she realized that she had possessed the body of the villain Seria, in a romance novel, she had a hunch about the future and decided to live low.

She would avoid kidnapping and harassing the original heroine, hence preventing her death by decapitation at the hands of Kalis, the second male lead.

In order to avoid that, she had to fix her bad relationship with Kalis and even healed his injured arm.

Thanks to that she got engaged with him, so it’s all worked out.
Finally, the original heroine returned, and her husband, Lesche, should be on good terms with her now.

“I’ve been waiting to escort her, so…”

Lesche asked, resolutely cutting off Kalis’ words.

“Miss Seria, it would be better for you to choose. With whom would you want to go with?”

Something was strange.
The original, wasn’t it perfectly fine?

I became a professor in a game by accident. To make matters worse, I even messed up the difficulty settings. Now, I’m stuck playing on Hell Mode. A world on the brink of war with the Demon King. An Assassin Department where mu*der is legal… as long as you aren’t caught. I thought I’d have to claw my way through just to survive in this wretched place, and that was the case at first. But nowadays… “No matter how hard I try, I can’t be like you, Professor… How do you do it?” “Please… become our god.” “What do you know? What is it you know? Why do you make me want to live…?” One by one, everyone at the academy began to obsess over me.
