enjoyed it but didnt understand the ending completely.
At first i thought i didn't understand the ending if this film, but after few moments of remember some since at near ending. conclude that she didn't want to make the same mistake on running from another places to another, it not about earning 1 million yen. She's afraid of staying long in one place because of what happened in the past (putting herself in jail and having criminal record.). if you remember the scene where her brother send a letter, saying he stood up on those people who bullied him and he said that he learned it from her and in the end of letter her brother said that he won't take the exam and will not transfer in private school because he want to face the problem and solve it and will not running away like his sister did. That's what Sato realize. So in the next town She had to take a courage to face the difficulty like he's brother do.
BTW Happy Birthday!
