Kamakura all-girl high school's newest student is this little crybaby Fumi Manjoume. In the morning of the school's welcome ceremony while on the train in a chance encounter she meets a girl from a different high school, named Akira Okudaira. As it just so happens, these two girls were childhood friends who had not seen each other for 10 years until now. This meeting at the station on the way to school, brought tears to Fumi's eyes. Akira saying that Fumi hasn't changed much since they were kids softly handed her a handkerchief to wipe away the tears...

Through this chance reunion between these two childhood friends, both Akira and Fumi make a promise to go to school together despite the fact that they attend two different schools, while still making other friends along the way. Almost as if they were making up for lost time, the intimacy between the two starts to deepen. Entering school and overcome with excitement, Akira and fellow classmate - Kyouko Ikumi - decide to join the drama club. Respectively, Fumi decides to join the literary club and along the way mistakens Yasuko - the cool, boyish upper classman who is part of the basketball club - as part of the literary club. Yasuko later decides to make a guest appearance at Akira and Kyouko's club.

Planning to back out of joining the basketball club, Fumi is asked out on a date by her senpai - Yasuko Sugimoto. While thrown off guard and a bit flustered, she is surprisingly happy on the inside. However, Akira is invited to a mixer by her classmate Kyouko, whose fiance Kou Sawanoi, will be attending. For some reason, maybe the anticipation of meeting Kou, Akira left her home nervous and on edge. Meanwhile on that very day, Fumi and her senpai had a surprisingly quiet and pleasant time together. As the distance between them began to shorten at the library, they leaned in for their first kiss...

After being asked by Yasuko to accompany her to school, Fumi worries about who to walk to school with: her childhood friend or girl who she likes. When revealing her predicament to Akira, she laughs and they come up with a solution to her problem. In the meantime, Kyouko starts to inquire about Yasuko...
