With Ana now setting the rules, the pair begin a true relationship but as stories about Christian's past are revealed and Ana is introduced to some of the women that involve his past, neither party know exactly how they'll make their relationship work without sacrificing certain aspects. Christian begins to realise that his feelings for Ana run deeper than the usual dominant / submissive roles that usually define his relationships. Time passes, Christian continues with his business lifestyle and Ana starts a new job at a publishing house and the former lovers reunite whilst at an exhibition of photography put on by one of Ana's friends. Still wishing to go ahead with the relationship, Ana finds out just how far Christian is willing to go to get his thrills but realises that she can't be with a man who inflicts that level of pain on someone they care about. As dark secrets were uncovered, it became known to Ana that Christian was into BDSM. Though from completely different backgrounds and living entirely different lives, the pair were attracted to one another and they began a relationship - one mainly brought about after Christian seducing Ana, his latest younger woman. Christian didn't know just how naive Ana really was and Ana didn't quite understand just how dark Christian's thoughts ran.
