Oshiegoto: Doujin Kyoushi to Tensai Gal

A woman who creates doujinshi in her personal time takes a job as an art teacher at a high school, where she encounters a student who is both a stylish gal and a skilled portrait artist. The student admires the teacher's doujinshi and compliments her work, which pleases the teacher, though she tries to conceal her involvement in doujin circles. To maintain her secret, she claims the work is done by her older sister, also named Sachi. The student then expresses interest in learning to draw in the style of the fictional "Sachi."
