Yeah! I remember when YA was in the early hype it was all about it, not only vampires but also angel (I think there's popular one featuring this), demon, werewolf, android, and anything imaginable which are fuckable enough. It reminds me of Wattpad genres of Vampire and Werewolf which I think most of it composed of inter-species YA romance stuffs, instead of the one not focused in romance.
Not because I hate it... I avoid that kind of stories because it sometimes can be so plain and follows same formula: girl is "averagely pretty" and leads a mundane life, until one time supernatural hot boy appears and tells he needs girl for a mission, girl knows her worth and purpose, butt kicking romance, and so on... so on... Bonus point if the guy is tall, dark, and handsome, has troubled past, plus badass but can be sweet.
Plus not to be like that guy, but I don't see the appeal of romance-focused story.
