My Genius Sister is Only Seven!? - Chapter 242 - How Do You Know?

Kota Sakamoto—virgin weeb, social reject, and hentai game addict—gets sucked into a perverted dungeon world straight out of Carnal Labyrinth EX, the 18+ erotic strategy game he secretly 100%-cleared.The catch?All eight of his hot classmates and their strict MILF teacher got dragged in with him.The other catch?They hate his guts.Worse still, this dungeon world is exactly like the game—every level a twisted, orgasm-fueled survival puzzle where failure means death by overstimulation, lust-monsters, or trap-triggered climaxes that literally drain your soul.He’s the only one who knows how to survive.They either listen to the virgin... or moan themselves to death.Bondage plants, lewd slime traps, fetish trials, and orgasm boss fights await—and the only way forward is obedience.What starts as reluctant cooperation turns into obsession, as each girl slowly falls for the boy they once mocked...…the virgin who’s now their dungeon master.

I wanted to be the hero but I knew in my bones that I couldn’t.

Ten years after the end of the world I struggled desperately to survive but I fell to my knees in the face of a great destiny.

“If only I were given one more chance.”

And like a miracle, another chance came.

It’s not like before, when I gave up and let go of everything.

I’ve had enough of playing the supporting role, now it’s time to rise above everyone else.

I’ll be the main character and reach for the stars.

Su Yan adored Xie Yu for many years and finally got what she wanted, but Xie Yu ran away on the wedding day, making her a laughing stock. At that time, Bai Xingfan appeared in front of her. He held a black umbrella in his skeletal hand to shield her from the heavy rain, and the other hand stretched out in front of her with a gentle and determined voice: “Don’t be afraid, still With me.” Su Yan was stunned with tears in her eyes for a long time, and finally, she reached out to Bai Xingfan.
