Manga no Tsukurikata

Asuka became a manga artist at 13 but hasn't published anything since, and is now 19 years old. After finishing high school, she becomes inspired by the work of Sachi and quits her job to pursue manga again. To gather material, she starts a relationship with Morishita, a former coworker who is in love with her, as romance genres are currently popular. She later discovers that Morishita is actually Sachi.
