The story was sweet, a bit slow paced, and then, boom! I feel towards the end the story was a bit hurried, like jumping and skipping the good part. I wish the writer gave more details about how they built their relationship after "I Love You". And i wish there're more suspense. 
 The sex scenes were good. They quite vivid, and steamy, but at the same time full of feelings and emotions. I like it. 
 Although i cant quite relate with Grey, but maybe because you upbringing was something ingrained within you, and other people, unless who had the same one, would find it hard to understand.
