As Koyume first serialization begins publication, Tsubasa goes out with the other girls to get inspiration for a slice-of-life chapter for her manga. Later, Koyume worries that she has gained weight and desperately tries to lose it, which starts to have an effect on her manga. After that problem is resolved, Tsubasa loses her manuscript at school, prompting the girls to search for it, only to end up finding Miharu's old yaoi manuscripts instead.
