Do you know what’s sad? The fact that the person Viktor Krum would miss most is the girl he met that year. Like he had no other people that he cared about? Family? Friends? Parents? They got Fleur’s little sister why not someone he cared about? Does this mean that Krum has such a shitty life back home and in Durmstrang that the person he’d miss most is the girl he only just started dating? And if so it’s sad that they break up. 

Either he cared deeply enough about Hermione to the level that he would miss her most out of all of his family and friends or he has no one else in his life that he’d miss. Either way it’s heartbreaking.
