Monthly Girls' Nozaki-kun

Chiyo tries to advance her relationship with Nozaki when she finds that she still has not given him the chocolates she had for Valentine’s Day. Chiyo, Nozaki and their friends attend a summer festival where Chiyo is reminded of the time when she and Nozaki first met.

Hoping for some ideas for his side characters, Nozaki has Wakamatsu accept a movie date with Seo. When Hori suggests doing a musical production, Kashima scrambles for help as she is tone-deaf and cannot sing. During rehearsals, Hori duels Kashima, but when Mikoshiba is volunteered to do a part, Hori realizes he resembles Mamiko.

Kashima has been driving Hori crazy with her antics, but she gets confused when she discovers that Hori and the guys have been reading Yumeno’s shojo manga and taking it rather seriously. Hori challenges Nozaki to do some backgrounds, but Nozaki frustrates him when he does not get the perspective right, placing boxes under his characters to compensate. Thinking Hori aspires to be a princess, Kashima replaces his clothes with something more feminine. When Hori collapses during a rehearsal, Kashima carries him to the nurse’s office while wearing a bull mask.

Nozaki sees Hirotaka Wakamatsu, his junior from middle school when they were on the basketball club. Wakamatsu tells Nozaki about being stressed out and unable to sleep because of Seo's antics, however, when he hears a recording of Lorelei's singing, he immediately falls asleep and feels refreshed. Using Nozaki's shōjo manga as a basis, he confronts Seo, but she interprets his actions as gestures of friendship. Later on, Nozaki gets a fever and sends the text message "SOS" to Hori, Sakura, and Wakamatsu. The three team up to help Nozaki with his manga, but are challenged with the task of applying screentones.

Mikoshiba asks Nozaki if he can stay over in order to seek his advice regarding girls, however the "girls" turn out to be heroines of a dating simulation game. As they try out the game, they realize that the protagonist's best friend, Tomoda, has been caring for him throughout his adventures, which prompts Nozaki to make a story about their friendship, which appears to Sakura to be a Boy's Love-genre story. Later, Mikoshiba is invited to attend a mixer but is too shy to know what to do there, so Nozaki and Sakura practice with him.

Nozaki introduces Sakura to his friend Mikoto Mikoshiba, a popular and flirtatious guy who Sakura soon learns is actually painfully shy and is often ashamed of his own words. He spends a session at Nozaki's place eagerly waiting for Sakura to ask him for help although he is too shy to prompt her. Sakura learns that Mikoshiba's artistic specialty is adding background decorations such as flowers, and she discovers that Mikoshiba is Nozaki's model for the heroine of his manga. Nozaki later asks Sakura if she has any friends who might fit in a shojo manga. Sakura introduces them to Yuzuki Seo, a girl who the guys discover has a habit of being insensitive and oblivious (not reading the atmosphere). However, she has an angelic singing voice, of which she is nicknamed the Glee Club's Lorelei.
