The common route is 1-4 chapters and the specific LI routes start at 5-10 so I think we're not at a specific route yet. When Nicholas texted you at the end of chapter two, what did he say? Because for me he was acting pretty suspicious, and when he was texting me he said "because of you" "now I" and then he erased the message that he was about to say, so then he just said that I need to tell Daniel what happened. So I lowkey think that MC might have actually kissed Nicholas and not the other guys because the way he was texting was really weird. Also the fact that in the game MC couldn't even remember ANYTHING at all about the fact that Nicholas actually did come by their apartment to get the book but she somehow remembers other little details about the other guys when she was alone with them?? So that's also why I'm suspecting that Nicholas might actually be the guy she kissed.
Sorry if this is a bit long and confusing.
