Nana K is living an easy life as a student until her three closest friends decide that they are going to go to study art in Tokyo. It would be harsh to say Nana is untalented, but she isn’t good enough for university yet; and so she faces a future without her friends, on her own again.
This was a really great episode, perhaps too dramatic in places, but ultimately that’s what we expect from NANA.
It begins with Nana K back to her old self; completely reliant on other people, acting like a spoilt kid. It ends with her having made some important realizations about herself, notably her feelings for Shoji but also that she has so far gone through life almost exclusively depending on others. When her friends turn around and talk about leaving for Tokyo, it’s obvious she has no ambition of her own and despite desperately trying to follow them, Nana is forced to confront this fact.
It seems this was the conclusion to the Nana K backstory and it ended well, at an imporant turning point for her life.
