One Million Yen Girl

Suzuko Sato is an unremarkable young teen who has trouble fitting in. While her younger brother is often praised for his smarts, her family & neighbors have nothing to say about Suzuko.
One day at work, Suzuko's co-worker offers to become roommates with Suzoko. Suzuko jumps at that chance to move out of her parents' house, and they set out to find an apartment. Unfortunately, Suzuko's friend never mentions her plan to have her boyfriend Takeshi live with them - until after they sign the lease on their apartment. Making matters worse, on their big moving day, Suzuko finds her co-worker a no-show, but her boyfriend Takeshi sits glumly in the apartment. It turns out that the couple recently experienced a falling out, with the boyfriend still intending to move into the apartment without his girlfriend. Things then hit the boiling point when Takeshi throws out Suzuko's cat. Suzuko retaliates the next day by throwing away all of his belongings and then quickly moves out before Takeshi returns.
The next day at work, Suzuko is visited by detectives who ask Suzuko to come in for questioning. It seems Suzuko broke the law by throwing away Takeshi's belongings, and because of she is fined and receives a criminal record. When news of this spreads to Suzuko's neighborhood, Suzuko suddenly feels even more alienated. She then decides to save up one million yen with the goal of moving out of town. Suzuko then plans to find another job, save one million yen, and then move on to the next town.
