Wandering Wandering

On a rainy evening, 19-year-old university student Saeki Fumi happens to meet 9-year-old Kanai Sarasa in the park. Sarasa is soaking wet. She is separated from her parents and lives with her aunt, but she tells Fumi that she doesn't want to go back to her aunt. Fumi takes Sarasa to his apartment and they live together for the next 2 months. Fumi is then arrested for kidnapping. He is labeled as a dangerous kidnapper and Sarasa is labeled as a poor victim. 15 years later, Sarasa and Fumi happen to meet each other.
