Ron Weasley.
Hermione
Harry falls in love with Ron's sister, they get married and Ron marries Hermione.
No, Hermione used Cormac to make Ron jealous. But Cormac did like Hermione though.
Hermione like Viktor Krum from Durmstrang. She didn't fancy Cedric but had no objections to him as a person as she never really knew him.
That's how it is the books.
Harry loves Hermione like a sister.
It is 'Snape', and no, he is not.
Hermione Granger
Hermione Granger and Ron Weasley got married because they love each other.
In the official books, Snape is not in love with Hermione at any moment. Sounds like fan-fiction.
Because Hermione belongs 2 Ron and always has loved Ron not Harry
Love has no reason.
