There's Something Wrong With You, My Lord! - Chapter 12: Stunned Stupid

Thousands of years ago, a small planet collided with Earth and destroyed the world. In five days, ninety percent of humans had been wiped out, leaving behind the last ten percent to earnestly struggle on death’s door.

Jinyu was one of those people who survived. Due to a special heredity trait, he could understand beast language. After the apocalyptic disasters, Jinyu had been living for a month with the few small beast brothers that he’d subdued. Previously, Jinyu had thought that he would live like that until he died. Yet, inexplicably, one day he opened his eyes to find that he was in a monstrous, lawless world that was full of vitality and life.

Jinyu’s transmigration into the future let him skip over almost one hundred thousand years. In the year 106825, beasts rule the galaxies and ‘pure’ humans are extinct. As the one and only ‘pure’ human left in the entire universe, Jinyu braves this new chaotic world to find a place for himself and thus begins to work at Beast Store number 138.

Sheng MuMu was transmigrated into a novel.

While others transmigrate to become celebrities, she ends up becoming a stepmother to a 17-year-old young master of a prestigious family?!

She wants to escape! But wait, what’s this? Pretending to be his wife for a monthly allowance of 500,000 in pocket money that can be freely spent on her card? Suddenly she doesn’t mind so much!

Everyone guesses: “She’s just a stepmother, how much could he really care for her? President Qi just brought a woman home to take care of his son.”

On the day of the banquet, surrounded by the media, Sheng MuMu hooks her arm around the man’s neck and sweetly calls him: “Dear~”

The man’s eyes darken as he pulls her slender waist closer, naturally dispelling the rumors.

Then people say: “She’s just a brainless trophy wife, just a pretty face.”

Sheng MuMu: “You dare call this 700-scoring top-scoring beauty from the city just a trophy wife?”

She opens a flower shop, becoming an internet sensation with people lining up to take photos, earning pots full of money; she starts a brand, appearing on the cover of financial magazines’ annual rankings.

And after that…

Tsundere stepson: “Better than a real mother.”

Vicious mother-in-law: “Daughter-in-law, when are you taking me square dancing?”

Until one night, Sheng MuMu’s earlobes blushing as she pushes away the man pinning her against the wall.

“President Qi, our agreement is just a contract marriage. ”

The man’s eyes narrow as he loosens his tie and leans down:

“The agreement? I tore that up long ago.”

Sheng MuMu: “You…mmmph”
