Tomo Aizawa, a tomboy girl, confesses her love to her childhood friend Kubota Junichirō. However, he mistakes her confession as a casual assurance of friendship between boys, disgruntling her. Later on, Tomo asks her best friend Misuzu Gundo for advice. However, Misuzu says she has rightly portrayed herself as a boy because of her lack of femininity.

Tomo is shocked to learn that Junichiro and Misuzu briefly dated in middle school. Tomo then decides to invite Junichiro out on a date herself, with help from Misuzu and Carol.

Tomo wants to experience some girly interaction, like hugging and hand-holding, so she tries it with all of her girl friends.
