I highly recommend watching this first before watching season 2. It is certain that the series from Nadao must have very good cinematography, I was amazed by every shoot. my favorite scene is when oh aew and tea hug on the beach, somehow the scene feels very powerful. The side story is very simple but in some scenes it can be very powerful. And the tone of this movie it's makes more warm. And the romance in this story i srelally cute, like idk i just love it, they give us really natural skinship. I just love it the way nadao gave us side story, it's really worth it to watch.
