I also thought of Lakein, but the more I think about it the more I am convinced that it is Lexi again, I believe that the rapprochement between the two can start from a new plane trip, the scene could be very nice, with the two pretending a new presentation and that this time they pretend to recognize themselves as childhood friendship. But the truth is that a dim scene would be a story finale. I don't know how many chapters Nyx has planned, but I doubt there are so few. Lakein, however, would be a new drama related to Lexi and I think there are already too many around her, if you put Lakein on Erynn and Layla, poor Lexi ends up exploding. Also, Lakeyn gives me no idea that I'm a girl looking for drama and steady relationships. Although aesthetically she is my type, one of her arrives on a permanent basis would seem strange to me.
Of course, there is another person who could be related to Lakein without us knowing. A beautiful tattooed MILF, who maybe went to get a new tattoo that week, and who is now coming home. Difficult, I know, but I hope so.
