Yes it sucks that they are brothers but it is literally in the title and the cover implies they will end up together. You have all the signs there, and therefore have the choice to not read. Everyone has every right to complain when they don't like something, but to say "I hope it doesn't turn into incest" seems rather silly because it is obvious from the start that it will be. It's like going to see a horror/slasher movie and saying "I hope no one dies" or going to a musical and saying "I hope there is no singing or music". Silly silly silly.
