Here's why:
* Tom Riddle was a dark wizard who sought power and immortality. He was incapable of love and saw people as tools to achieve his goals.
* Ginny Weasley is a brave and kind witch. She is loyal, strong, and values love and friendship.
* Their interaction in the books is minimal. Tom Riddle possesses Ginny's diary in *Harry Potter and the Chamber of Secrets*, but he uses it to manipulate her and drain her of her life force. There is no hint of romantic feelings on either side.
The diary's influence on Ginny is a crucial plot point, showing how dangerous and manipulative Tom Riddle was. It highlights the stark contrast between their personalities and values.
The idea of Ginny and Voldemort being in love is a misinterpretation of their relationship and a dangerous fictionalization of a complex and disturbing character like Tom Riddle.
