I love romances and smut and deep, slow burning passion between characters. If it's written well, that is. Is a book only introducing a character as a side note so that the main character can fuck someone? Get that out of my face.

But if the love interest turns out to be a real character that has a real connections with them, then I'm all for it. I love romance side plots between detectives and their sidekick because most of the time they're best friends and already share a great chemistry. Not having this and instead getting a badly written no- name character would make me feel like I've wasted my time tbh.
