Mahiru no Polvorón

The nine-year-old girl Rutsubo doesn't like her father, and has made up her mind to never forgive him for abandoning her right after she was born. But when her guardians take a two-month vacation, she's forced to live with him for the first time. Live with him, fine—but that doesn't mean she has to talk to him. This is the story of a silent, withdrawn girl and the complicated father who hopes to win her over.
