Did Natsume go to the foreign fruit shop on the corner to study abroad? What is the wish of summer purpose?

Natsume has gone abroad to study. At the last dinner, she told Shicun that she would not study abroad until Shicun realized her wish.

At the end of the movie, ten villages found their ex-wife with their own cakes, and they should be reunited. This is Xia Zi's wish ~

So Natsume saw this scene in the car and left with his luggage ~

Natsume did this to help ten villages get out of the shadows. When the car accident happened, Shicun gave up making cakes, which made no sense. It was Natsume who gave him the courage to start over and find his ex-wife. Personal opinion ~
