Sawa Mitoma is spending summer break with the Sohmas at their vacation home/cottage. She is becoming friends with the Sohmas, especially Shiki. She and Shiki go to the aquarium together one day on summer break. Sawa is very happy and enjoys her time at the cottage. However, summer break ends and they all return to school. It was revealed in the second book that Sawa's mother is gone for long periods and is verbally abusive to Sawa. In this story, it is revealed that Sawa's mother hurled insults at her friends when she was a young girl and that's why her friends said mean things and left her. Sawa wonders if her mother has done that to the Sohmas (or anyone else). Also, it is revealed that Sawa fell down some stairs while alone and was bleeding from the fall. Shiki is the one who found her crying both before and after she had fallen. Sawa had left home to be alone after her mother left home after promising they would go out together. Her mother sued Shiki's father and the Sohma family. Shiki had thought of her ever since. The story ends with the School Festival. Shiki comes to the festival to hang out with Sawa and his family.

Sawa Mitoma is starting at a new high school. She doesn't have very high self-confidence and tries not to be notices or cause any trouble. She is always looking down. However, when she is late for school on the first day, a handsome new classmate named Mutsuki, sticks up for her and over time he and his friends/family raise Sawa's self-confidence. Sawa learns that Mutsuki and his friends/family are Sohmas and Mutsuki and Hajime are Vice President and President on the student council. They invite her to be the first-year representative on the student council. Also, they invite her over for dinner after school on the 29th, which is meat day (because the Japanese word for meat and the word for 29 are similar). Over time, Sawa Mitoma gains confidence and feels like she is starting to fit in with the Sohmas.
