If two characters end up falling in love with each other in the books that is fine, I don't care, it is nice to see the hero love someone and as long as it is written well I am alright with it BUT there are times where I have read a book series and we have something like this:
Morganville Vampires: Shane and Claire first meet each other when Claire is looking for an off campus place to live because the mean b***h at school and her flunkies are basically making her life a living hell, so much so, in the girls dorms where she was staying she was pushed down the stairs and thus needing a place off campus so she only had to put up with them (mostly) during school hours. So Claire searches the local listings for a place she can pay rent at off campus and finds that the Glass house are looking for someone and haven't found anyone suitable yet so she goes over to the house, knocks on the door, no one answers so she breaks down and cries and then one of the residents turns up, asks whats wrong and she explains the situation, invites her inside and says that her and the other two living at the house will have to have a house meeting to decide but she (Eve, the resident) hopes that she can stay.
So stuff happens, Shane comes in, doesn't take more then a few seconds of looking her over and basically ignores her whilst shes there and when asked if she could stay he was already making his way upstairs and more or less said he didn't really care so they took that as a yes BUT later on in the book (book one) these two, Shane and Clair, have little to no interaction and then, out of no where, they are madly in love with each other, they share a kiss and all of a sudden she can think of no one else she would rather spend her life with and the same goes with him, they are instantly soul mates and so carrying on with the series, every time they kiss, have sex etc it is basically me rolling my eyes going "you shouldn't even BE together! Or at least you should of waited till the end of the second book or something!" Because I know love at first sight can happen but come on! At least BUILD on it, he didn't care about her five minutes ago but now, little to no interaction it is soul mate city, WTF!?!
Vampire Academy: Rose, guardian in training, falls for her mentor, professional vampire guardian falls in love with Rose but is 27 and Rose is 17 and so they can't be together because the school obviously won't allow student/teacher relations but as soon as book 1 starts we have Demitri starting to like Rose because he sees a bit of himself in her (she is willing to throw herself in front of her charge without thinking twice and regardless if she is out numbered) and that is basically what the author was getting at though it didn't really come across as that but whatever, its fine, I guess I can see that, but then we get to her having a topless scene and THAT is where he stares at her half nakedness for a bit and THAT is where we get him actually liking her more then just a student because, and I (sort of) quote, "I am probably one of the very few girls at this academy that looks good in a bra." Don't get me wrong, if there was more then just subtle (and I mean subtle) hits that HE liked her then fine, whatever, but she mentions how hot he is and blah blah blah but that is her, HE doesn't basically show he wants more from her till that scene, sure he isn't around her 100% of the time BUT when he is he doesn't show he cares more about her then just the normal teacher/student relationship (even when they do train together in privet) it is just seeing her in a bra that seems to awaken his feelings for her.
Seriously, I am all for love and what not in books but the least they can do is not rush it, if the series goes for 7 books make it grow, build the relationship up between the characters, just not go "we need two characters to fall in love in five minutes, how can we do this?" And thats it, do NOT force it and rush it! It is more believable if over time their feelings grow but to basically have one book push two characters together in five minutes and the other two can't be together but love each other in half an hour because he realizes that she looks hot in a bra does not make for a great relationship to be based off. And for VA, because they can't be together they tip toe around the fact they like each other and yet Push each other away which is also a pain in the a**, I understand why but it is annoying also which means that they should just ignore their feelings altogether till after she graduates OR they get together and leave the school, either way it makes seeing them together when I am reading the VA books a tad annoying.
