[Harry Potter] My Whole Family Transmigrated

After Holly transmigrates into the body of Miss Horadell Selwyn, she has to bury herself in her studies from a very young age to survive in a perilous magical world. Like the other children in the Selwyn family, she keeps to herself.

Holly: "Wow, is this the standard of manners in Pure-blood families?"

That is, until she turns five and hears her eldest brother, in perfect Mandarin, clearly call their father a "dumb*"...

She has no idea that this is only the beginning of everything falling apart.

When she nervously stops her eldest brother and asks, "Odd numbers change, even numbers stay the same?" her second sister calmly answers, under everyone's astonished gaze, "Look at the quadrant of the sign."

"Rather than stopping the boiling water by removing it from the pot?" her third brother asks cautiously, glancing around.

"Just gobble up the gold at the bottom of the cauldron!" her eight-month-old baby sister answers, still lisping.

Family...

A Hufflepuff Selwyn receives a Howler.

The Slytherins are eager to see how the noble Pure-blood families, especially the Selwyn family, who follow the Dark Lord almost fanatically, will treat the oddball who ended up in the "house for useless people."

But then:

"How dare you bring hard liquor into the common room to share!"

"Do you know how badly you scared Professor Sprout when she saw a whole group of people lying on the floor?"

"As a member of the Selwyn family, could you at least think before you act?"

"And though it pains me to say it, congratulations on getting into Hufflepuff. It's a good house."

The little snakes: Why isn't this what we imagined? But there really are so few people at the Hufflepuff table today.

Premise: Be the master of your own life.
