Viktor Krum is framed as a gentlemen by the narrative, despite the fact that much of his behaviour comes across as worrying and borderline-grooming. The age gap between him and Hermione was bad enough, but his interest in the fifteen-year-old Ginny Weasley when he himself was in his early-twenties makes me suspect that he actually has a thing for underage girls.
Also, in DH, his attitude comes across as incredibly entitled, as if he thought his status as a Quidditch player entitled him to all the good-looking women around him.
I don’t like Viktor x Hermione at all. When you re-read the series as an adult, his attitude towards her comes across as very creepy. Especially when he confronted Harry in the dark Hogwarts grounds because he felt threatened by the fourteen-year-old boy Hermione was best friends with.
Thanks for the ask, anon! Keep sending me asks for unpopular opinions, everyone!
