I think it's really good how Nomiya acknowledged that getting the driver's license was a huge first step for him and that he's improving bit by bit.
What I also liked and found quite interesting, was his line to Natsumi about not wanting to be the kind of person who upon meeting her some other time somewhere down the line, would look down and turn away.
I can definitely see the improvement in Nomiya's behaviour and I find the dynamique between Natsumi and him very interesting.
