花物語

Fumi Manjōme is starting her high school life at Matsuoka Girl's High School. Her family moved back to Kamakura, and when she was in grade school, her best friend was Akira Okudaira; Akira is starting high school at Fujigaya Girls Academy, a prestigious institution, and meets a girl in her class named Kyōko Ikumi. On the first day commute to their respective schools, Fumi and Akira run into each other, but do not realize this until after Fumi and her mother pay a visit to the Okudaira residence. Later, Fumi discovers that her cousin Chizu is getting married, which comes to a great shock to her as Fumi has feelings for her cousin.

春の嵐

Trying to figure out what club to join, Fumi chances by the literary club when a handsome upperclassman exits, and invites Fumi to join. Later, the girl introduces herself as Yasuko Sugimoto, a member of the basketball club, and Fumi joins that club immediately. At Fujigaya, Akira and Kyōko join the drama club, though they are only going to be working backstage for the upcoming adaptation of Wuthering Heights. Yasuko is asked by Fujigaya's drama club to play Heathcliff, and Fumi comes too, along with her friends Yōko Honatsugi, Misako Yasuda, and Miwa Motegi from Matsuoka. Fumi walks around the Fujigaya campus, entranced by the architecture and atmosphere, and sees a crying Kyōko exit a room.

朝目覚めては

Yasuko comes out of the room Kyōko just exited and asks Fumi to share a talk outside. Fumi tells Yasuko she is leaving the basketball club for lack of aestheticism and Yasuko expresses regret for it. Yasuko asks Fumi on a date before Yōko jumps in saying it is time to leave. Kyōko invites Akira on a group date organized by her fiance (in name only) Kō Sawanoi, but Akira's older brother Shinobu embarrasses Akira to tears during the date when Kō realizes a man in sunglasses has been staring at them all day. During this time, Yasuko and Fumi are on their date, walking around town and take in a view of the sea. Akira later yells at her brother for embarrassing her, though Shinobu merely expresses concern for a man taking his younger sister home. Fumi formally joins the literary club and afterwards Yasuko takes Fumi to the library room where they share their first kiss.

青春は美わし

Yasuko and Fumi become a couple and Yasuko wants to start going to school in the mornings with Fumi, but Fumi realizes too late that she already made that arrangement with Akira beforehand. Fumi wants to continue just going to school with Akira, but in exchange, she and Yasuko will have time together after school. Fumi resolutely tells Akira that she still wants to go to school with only her and in the process comes out to her about her relationship with Yasuko. Akira at first does not know how to respond, but after seeking advice from Kyōko decides the only thing she can do for Fumi is support her. Yasuko and Fumi, along with Yōko, Misako and Miwa, go back to Fujigaya where Yasuko takes part in a read-through of the script for Wuthering Heights and greets the drama club's adviser Masanori Kagami. Fumi wonders about the "Mistress of the Library" story Yasuko told her and who the involved parties were.

前編)

Fumi confides in Akira that she suspects Yasuko is in love with another person, and after school Fumi learns that Kyōko is in love with Yasuko. Fumi does not go with Yasuko to rehearsal since she feels awkward being around Kyōko. Akira notices that Yasuko is very popular with other girls, and sees why Fumi would not want to come. Kyōko realizes the other girls are not actually in love with Yasuko. Kyōko had asked Yasuko to treat her like nothing had happened between them, but Kyōko says she was merely acting strong. Yasuko goes to see Fumi at night and gets her to agree to come help with the reception desk the following day. Akira chides Fumi for forgetting to tell Yasuko she has been feeling jealous of the attention Yasuko has been receiving from other girls.

後編)

Akira is embarrassed when her parents and brother come, and she unwillingly goes with them to the dining area. Yasuko consoles the lead in The Little Prince, and by the time that play has begun, Fumi goes to buy a bouquet of blue flowers for Yasuko. Meanwhile, the high school division is getting ready for Wuthering Heights. The play is well-received, and when Fumi leaves to give Yasuko the bouquet, she sees Yasuko crying among the other actresses after Kagami thanks her for a job well done.
