I appreciate your response and Im glad you didnt take the comment personally. But I just wanna say the character who was fantasizing about the orgy is not an LI correct? If thats the case its not NTR and its not even cheating for that matter because it doesnt even actually happen, But my main question to you is dont you want to do something fresh and unique with unexpected twists and turns? To me thats what makes an interesting story. Many of these characters are supposed to be vampires and vampires are savagely violent and very sexual in every movie and story they are in. Right now this is kind of looking like an amateur version of twilight its the same old human and vampire fall in love. My favorite part was the dynamic between the Female MC and the bad guy because they're rivalry/conflict has the potential to be very interesting. Im not saying there has to be a sex scene between them( although that would be interesting) but if he was able to bite her for example and get some of her powers and become the ultimate enemy that would make the story way more interesting as well as give the characters a strong motivation to eliminate him. And it would make the final Showdown between the 2 MC's and him to be way more crucial and more emotionally investing. Thats just my thoughts on it. Either way good luck with it.
