Suterareta Yuusha no Eiyuutan - Story 2-9: 『Changing of Floors』

I transmigrated into a novel and became the villainess, Serina who comes from the noble Ducal Melford family.

As a well-to-do character, I tried to mind my own business, but the story had other ideas. A self-proclaimed mother brought back a boy – the duke’s heir and a genius wizard – intent on brainwashing and blackening him.

The contents of brainwashing are two things:

1. Obey our family.

2. And fall in love with Serina.

Thanks to that, the brainwashed twisted yandere is obsessed with me…

I can’t do this. I have to undo the twisted character’s brainwashing!

By the way, what’s this situation?

“Now that the brainwashing is gone, I’ll do as I please. So Serina, please, let’s do our best.”

I’ve solved his brainwashing… but why does he seem even crazier than before—

Did I make a mistake?

Ji Nai-tang paid attention to Cen Muqi for 12 years. This secret love had been hidden in his heart. When he finally couldn’t hide it, he sent himself in front of Cen Muqi, pretending to be a pig to eat the tiger and step by step planning to trap the golden thigh.

Ji Nai-tang: It is not that I look good, it is that you make me look good.

Cen Muqi: It turns out that it is important to have a boyfriend who will take pictures.

Ji Nai-tang: But you are not my boyfriend~

Cen Muqi: Can I apply for it?

Ji Nai-tang: What are you applying for?

Cen Muqi: Applying to be your boyfriend!

- Description from Novelupdates

When a terminally ill young man awakens in the world of his favorite childhood game, he realizes he isn’t the protagonist, the destined hero, or even a major side character. Instead, he has become an extra—a disowned noble barely clinging to relevance in a world where strength determines everything. Worse, his fate in the game was to die an early, meaningless death.Armed with only his knowledge of the game’s storyline and a common system that tracks his stats and skills, he is determined to survive. But mere survival isn’t enough. He remembers a hidden easter egg from a long-forgotten anime collaboration: the Mangekyō Sharingan—a power limited by game mechanics but unrestricted in reality.With Kamui as his trump card, he walks the fine line between fate and freedom, seizing power from the shadows while avoiding suspicion. As the protagonist and his allies battle against demons and unravel the game’s grand destiny, he secretly builds his own strength—manipulating events, mastering forgotten arts, and even forging ties with villainous factions.Will he remain a footnote in history, or will he carve his own legend in a world that was never meant to be his?

Su Wan is a Realm Destroyer. She shuttles to different time-spaces using the identity of the “Cannon Fodder Ex-Girlfriend”, dedicated to plotting how to happily tear apart the male protagonist and the female protagonist.

There’s no such thing as protagonists who can’t be torn apart, only Ex-Girlfriends who don’t work hard enough~
