If you're immigrating to another country with your partner, you should definitely watch this before you do so. It is a bitter pill to swallow so that you know what you're getting yourself into and be prepared for it. Watch it together and talk over it before packing your luggages together.
It really resonates me as immigrating to another country did brought various different challenges especially most of the time you're alone in some foreign land with different cultures, not to mention what even happened and missed while you were away from homeland.
The osts are great, so as the actors. Came across and watched this from knowing Kentaro Sakaguchi from The last 10 years and Kimi to 100-kaime no koi, his acting never disappoints.
Well, you just have another two more great movies to follow on if you haven't watched them yet.
