Harry Potter: The Star of Slytherin

Harem favorite + otome + one-sided crushes + ambitious madmen + strong female lead + Mary Sue (I’m a sucker for this stuff, so don’t hate on me)

Gu Fanxing used to be a Chinese cultivator. After successfully getting herself killed, she thought she could finally go to the Underworld, but instead she transmigrated into the world of a Harry Potter fanfic.

A second life, with the worst possible start: her biological father is in prison after being framed, her biological mother has been hit by the Imperius Curse, and a deranged adoptive mother has switched two babies. She becomes Vesper Black, the sole heir to the Black family.

An adopted younger brother she takes in along the way (an original character); The Chosen One’s sister, who’s like a slice of cake; a sweet filling between the twins; Percy’s guide; Cedric’s honey girl; Theodore’s fox; Hermione’s kindred spirit; Ginny’s big sister who shines like a star... (As for Ron, Oliver Wood, Draco, and the Marauders’ generation, such as Barty Crouch Jr., I may add them if enough people ask.)
