If you fail, start over

Overview

Yamaguchi's fellow teacher Shizuka, who teaches English, is also working nights at a club in the Ginza district. One of Shizuka's students, Noda, who has developed a crush on her, gives her a necklace, and later follows her to the club, where he sees her throw away his gift. The enraged Noda posts pictures online, exposing Shizuka's second job to the principal, who threatens to fire her. After a talking-to from Yamaguchi, the principal promises not to fire Shizuka if all of the 3-D students can earn at least 30 points on their English midterms. Yamaguchi gets to work preparing after-school study sessions for the students, but will it be enough to save Shizuka's job?
