HP: You Call This Transmigration?

What if Lily and James had more than just Harry, and Harry had a twin sister who could stay by his side forever? How would the world be different?

An Eastern girl transmigrates into Harry Potter's twin sister.

She looks like her mother, takes after her father, and has dazzling golden hair like no other!

Tina: Uh, well, this is pretty sudden. I'm a transmigrator, not a Mary Sue!

Harry: I keep feeling like my sister's on a different wavelength, but as long as she's happy, that's all that matters. (Sweatdrop)...

Draco: Not one of the Potters is any good.

The Weasley twins: Tina's a Gryffindor in Slytherin!

Tina thinks that, as an outstanding transmigrator, her main mission is to protect the angelic Harry and his dog-like godfather, save Snape and Dumbledore, send the noseless old Voldy to meet Merlin as soon as possible, bring everyone at Hogwarts together like one big happy family, and then live an easy, happy, fulfilling life...

Wait, wait, what is a Mary Sue even doing here? And why are people called administrators coming to capture them? I have to say, these administrators are really adorable together, hehehe.

Even stranger, once Tina got to fifth year, she frowned and realized things weren't so simple.

Where were all the advantages of being a transmigrator?

Where was the easy collection of all the Horcruxes and defeat of Voldy?

Where was the ability to know the future and crush the Death Eaters?

In the face of reality, all of these had turned to bubbles.

A few things to know before reading:

1. The early chapters borrow a little from other excellent works (such as HP: Transmigrating as Cho Chang and Born Noble). After all, this is my first time writing a novel, so any similarities in the content after second year are purely coincidental!

2. Romance is not the main focus. The female lead's final pairing is Draco. As for what happens in the romance before that, feel free to imagine!

3. I'll try not to bash or whitewash anyone, nor praise or disparage anyone. The story could lean Gryffindor or Slytherin. I'm a Hufflepuff, and everything here just reflects my personal opinions. When it comes to differing opinions and stances, you're always right. This clueless author's writing is garbage, so I'll insult myself first. Are you satisfied now? If it's not for you, feel free to leave!

4. I write mainly because I enjoy it, though I'll also adjust things to suit readers' tastes. If you don't like it, please don't flame me. Thanks!

5. You'll never guess how slow updates will be, but this story will absolutely not be abandoned!!! I'll finish it in this lifetime, for sure!!!
