You can legally get Clhoe and Lauren in CK1 in CK2 it's impossible and Norah is easy. I don't know what happens if you reject Norah in CK1 and what will happen in the cabin in CK2 but you have to be confident if you have another girlfriend or loyal if you don't have a girlfriend for Norah to accept you in the cabin.
Lindsey I think that in this latest update she is going the way of being a bad or loyal girl. More like a bad girl, but as I said in the end you won't be able to have them all. Now everyone knows MC has several girlfriends. And the only people who know these are the nerds, Amber, Norah, Riley and Aubrey know that we only go out with Clhoe for CK1, in the following updates you will see a lot of partying and many tears

At the moment it is not known which path to take and which story to follow, in short, do what you want without consequences.
