Ren Kuroda, a college student and hardcore gamer, finally conquers Eternal Souls: Last Judgment, an unbeatable RPG, only to be met with a strange message on his screen.

“Congratulations, Champion. Would you like to unlock the bonus stage?”

When he clicks "Yes," he is transported straight into the game world, reborn as Terence Ross, the overlooked third son of a minor noble family. Realizing he’s just an extra in a world teetering on ruin, Ren trains relentlessly to survive the coming chaos.

However, life wasn’t smooth sailing. 

He was soon engaged to Lilith Underwood, the girl destined to become the game’s final boss, the Third Great Calamity. To avoid her devastating future, Ren takes a risky approach, trying to make Lilith emotionally dependent on him in the hopes of anchoring her humanity.

Yet, his plan backfires spectacularly. Lilith’s attachment becomes a fierce obsession, one that could be just as dangerous as her dark powers. 

Now, as doom inches closer, Ren faces a double-edged crisis. He must keep Lilith’s powers in check while somehow surviving her unrelenting need to keep him by her side.

In a world where even heroes fall, can an extra rewrite his fate? Or will he be claimed by the calamity he tried to prevent?

Extra's POV: My Obsessive Villainous Fiancee Is The Game's Final Boss

The Ross Castle's gates opened as Lilith's entourage rode into the courtyard.

The Underwood banners fluttered against the morning breeze, their sigil, a great white tree on a black background embossed on it.

Fluttering above as if in welcome was the Ross family's sigil, a golden raven on a green field.

Ren stood waiting at the entrance, his posture relaxed, but his mind already working through the potential problems.

From what he knew of Lilith from visiting her, she wasn't… right in the head. So, his problem was how would he stop her… quirks from showing in front of his parents?

As Lilith descended from her horse, he barely had time to brace himself before she rushed forward, wrapping her arms tightly around him.

"You took too long to invite me." She murmured against his shoulder, her embrace lingering longer than necessary.
