Yeah, except they've been in Wollust long enough before college for businesses Nika remembers to have shut down a year or more ago - check out the bus trip to the hospital where they encounter Dave. And Nika was treated for the accident in Wollust. I also suspect Noji pushed them towards ZPR, but given the other college is elite, there might not have been a choice. Also, for Noji to push them towards their heritage (if that's the case) she still keeps them in the dark and prefers to hide them from Katie.
My guess is that they moved back because Nika's accident needed them to be close to the hopsital while he was recovering.
But also, Noji can't really be hiding them from the Zanes while also hanging out with their mutual friends to the point that it's an open secret at the book club.
For Nia to be in the same year, she also must've taken time off between school and college - maybe earning enough to make the fees.
I think Noji enlisted them at the college, she and Nika had a conversation at night in front of the house where she asks him why he agreed to go there if he didnt really wanted it. And this happening one year after ZPR took over the college cant be a coincidence. I think they just moved after high school?
I dont think it was ever about hiding them from the Zane's, it looks like some sort of agreement or deal to me but im sure the Zane's knew all the time where Nika and Nami have been and probably got updates about them too.
And if Noji really would try to hide them, there is no way she would invite Nami to the bookclub, i think at this point the possible physical danger for them is solved and thats why Noji took Nami with her. She was obviously still unhappy about Katie being there but she had to knew about the possibility.
I think Nojiko being secretive is more about Nika and his mental wellbeing at this point. Nojiko simply has no clue, she dont know if he's ready to tackle his past yet and from her and our (the readers) perspective, shes probably right about that. I dont see Noji being able to have a single bad intention towards Nika and Nami and i suspect her fear of a Nika/Nami relationship is born in the Zane incest.
She even tells Nika about her reasons imo:
And she isnt wrong considering Nika indeed had a breakdown at the bookclub and there wasnt even a lot revealed. We cant forget that Nika is a boy who kinda locked himself in his room for the last year and was highly unstable at highschool.
