I wouldn't call her "Kendra lite" though more like "Nyxmay lites lite" on her bad route Kendra is a full hendoist but Maryen got some deep affection for MC even on her "Neyram" route this has been clarified on this update just like Nyxmay got affection for MC but unlike her -for now atleast- there is no blood nor large scale tiny masscares.They are similar but with some dialogue changes and different sex scenes
One is all nice and "lovey dovey"
In the other one she is Kendra lite version so to speak, as in more abusive and possesive but not quite as bad as her.
