Twisted Series 4 Books Collection question

I personally love Christian and Stella, though I can understand why some may not like them. I think the overall best twisted couple is Bridget and Rhys for the reason being that I really felt that these two were actually in love and not just attracted to each other. I love how Rhys respects Bridget as a person and sees her as his equally, but he also acknowledges the position of power that she has and supports her. I will have to say my least favorite is Alex and Ava, i'm sorry! I felt like they were attracted to each other and weren't really in love. I think it has to do with the fact that their book is the shortest. I will say that I do enjoy them more in the other books, but I should have gotten that from their book not the others.
