[2] Akira Kuroiwa, a third year middle school student, falls in love with his new homeroom teacher, Hijiri Suenaga.

Written and illustrated by Junko Kawakami, Chūgakusei Nikki started in Shodensha's josei manga magazine Feel Young on June 7, 2013.

The series stars Kasumi Arimura as Hijiri, Kenshi Okada as Akira (in his debut acting role), and Keita Machida as Shōtarō.

Additional cast members include Yui Natsukawa as Aiko (Akira's mother), Yo Yoshida as Ritsu, and Mari Natsuki as Shiotani.

Despite that Akira is 15 years old in the series, the production opted to cast 19-year-old Okada as they could not hire an actor closer to the character's age.
