I think it helps, it's a micro society system...You'll end up with more or less confident after that but it's also true that your life could change drastically after your twenties, personality too.
Uuuhhh childhood friend route seems to be still there but dormant, I don't buy the "I only like my idol" lol
I want to Talk about the RAWs once again, in the latest chapter we hit a point that sounds like the climax trigger but it might end up being not much after all (like the previous 5 times when the drama went up to a 100) and return to status quo... But if not, I think Shino could try to make things more... intimate. It's always like this, first Shino gets a bit crazy, then Nozomi, then Shino, then Nozomi gets A LOT crazy then healing and now is Shino's turn again.
I think, I could see an ending but I don't want to make theories with RAWs
