I don't understand where the 1 star ratings are coming from because this was such a heartwarming drama about friendship, family, and community. It's a very comforting drama and I actually started badminton because of this--which I never thought was that interesting before!
EDIT: I just read some comments with 1 star rating. As a non-Indonesian who've been to Indonesia before, I know that the portrayal in Episode 5 isn't true. They're kind and warm people. But then not everyone has been to Indonesia and might misconstrue the scene in Episode 5 as a common behavior among Indonesians. I hope the writer has apologized and will be careful in the future.
