MiA definitely had the potential to be a model all along - you can tell how much he internalized by watching other models work with photographers. And as for the fate of Yo-ka and Yuuki's relationship . . . you'll see what happens in the finale chapter!

Subaru's lost love is an idea which, unfortunately, I didn't get a chance to develop fully in this fic itself (too much going on) - which opens up the possibility for a prequel!
