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 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.

After Tomo is groped by an old man on the bus, Junichiro suggests that she stop wearing skirts. Then Tomo meets Carol, an English girl that all the boys in school admire.

Tomo visits each of her best friends' houses. She meets Carol's mom, gets some help studying for midterms at Misuzu's, and... stays overnight at Junichiro's house?!

Junichiro recalls how he and Tomo first met and the four friends spend a day at the beach.

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

Misuzu sees that Misaki and Carol need help expressing their feelings for each other, so she comes up with a plan to get them together... but the results are far beyond what she expected.

Tomo has noticed that Junichiro is starting to act differently around her. They both try to sort out their feelings while seeing the summer festival fireworks together.

Tomo wants to earn money for a birthday present for Jun, so she works part-time at the ramen restaurant owned by Tanabe's family. Later, their class prepares for its presentation of "Cinderella" at the cultural festival.

Misuzu and Carol give Tomo an extra-girly makeover and send her to the convenience store, where she unexpectedly runs into Junichiro. Later, Tomo gets fired up for the school's ball sports tournament.

Tomo and Junichiro are fired up for the school marathon. They start out neck-and-neck at the head of the pack, but when they reach the girls' turn-around point...

Junichiro finally confronts his own feelings for Tomo, and Tomo questions whether she really wants the friendship they have to turn into something else.

Tomo begins to wonder why Junichiro always seems so calm and collected around her, even though she always feels flustered around him. Then she finds out that Junichiro made a certain deal with her father...
