I like Robert content in the first chapters actually, as I would like to think he’s quite realistic in a way that there are people like that irl, one who would use their position of power to their advantage, no matter how insignificant that may be. And I’d like to think my Lena was susceptible to that kind of coercion, particularly from her financial standpoint and from being pressured from Ivy, her best friend advice. Also, she’s just been harassed again from her old nightmare ex who she seemed to be in a sub-dom relationship already, I understand why she’d just go for it just for the sake of move on from that hurt in the past.
In my head she’s just weak and desperate at that time and just go along with the flow that one person takes advantage off. She loses a Will point if she let him come upstair that night afterall, if you guys remember. I think this is called a Will point for a reason (same goes with Axel shoots later, in some stat condition.)
But you know what, she also gains much confidence from that and seems to feed off being in control more and more to the point she does not need Robert anymore to satisfy her. She has become more independent, liberated and, in my opion, stronger as a result of that guy.
However if you want to just look on the surface as why would beautiful girl like her would lower her standard when meet this jerk and have sex have sex have sex then I understand why most poeple would hate him.
