Quiet and unassuming Mei Tachibana has spent her high school years without friends or boyfriend. A childhood incident in which her so called friends turned out to be toxic and shallow left her scared of disappointment, leading her to be cautious around people - too cautious. She encounters a popular boy named Yamato Kurosawa, who took an interest in her. Through their friendship and blossoming relationship, Mei ultimately begins to branch out and befriend others.
Since Mei used to be constantly bullied as a child and her classmates blamed her for an accident she never did, she decides to never befriend anyone again and all she needed to survive was herself. At first, she is viewed by others as "freakishly gloomy" and someone who "doesn't speak" but in addition to being anti-social and clumsy, she is observant, kind, honest, supportive, and funny. As she eventually falls in love with Yamato, she starts believing not everyone is selfish and finally begins to have true friends. When it comes to her career choice, she decides to become a preschool caretaker/ teacher.

When a stalker follows Mei to a store, she calls Yamato for help. When he arrives, he kisses Mei to get the stalker to go away. Over time, Yamato falls in love with Mei and they start dating. He cares for Mei more than anything and her feelings matter the most to him. Asami describes Yamato as someone who thinks of others more than anyone else, protects what should be protected, and cares for others despite having his own problems to deal with.

After Mei stands up for her, she learns to accept Mei as a friend and supports her through tough times. She ends up dating Masashi.

After realizing few people actually think of her as a friend even though she tries to please them by paying for meals and giving gifts, she finds true friendship in her childhood friends, Momo and Asami. In addition, she begins to ignore what others say about her and cuts her hair as a sign she is going to make her future decisions without worrying about others' opinions of her.
