it's a storytelling construct, having a character or characters fall in love with the MC (male lead in most cases) adds to the "hero" figure and to their appeal to a reader. OF COURSE the strongest, bad-assest, beautiful, unreachable (by others) female falls in love with him, he's THAT much of a bad ass and worthy of being a ML. If you don't like it take it up with human psychology.
For those who haven't read the novel, there will not be any romance. The story will not go off the car lane, dont worry ┑( ̄Д  ̄)┍
