Chihiro (Kasumi Arimura) used to work as a prostitute. She happened to stop by a seaside town and have a bento meal there. She loved the meal so much, she decided to settled down in the seaside town and work at the bento shop. She now greets customers with a smile at the bento shop and makes small talk with them. She doesn't even hide her past. Chihiro talks with customers about various problems and, through their conversations, they are comforted by her. Chihiro herself suffers from loneliness, which started with her family when she was little. By meeting her customers, she also faces her loneliness and gets over that slowly.—AsianWiki
