Ootani Rin, a girl from a poor family due to her father's gambling is attending a highschool on a scholarship. She has been taking care of her sisters and mother ever since her father ran away. Her school doesn't allow its students to work part time but she's not worried about it since all the students at her school are rich. However one boy takes interest in her, finds out about her part-time job and to keep him quiet she has to make him a bentou (packed lunch).
