Black Dog

Ha Neul has witnessed the cold reality of being a short-term teacher herself. The teacher who saved her life at an unfortunate school field trip accident was never fully compensated nor recognized by the school. However, she aspires to become a teacher one day and takes her first step into her first school. It’s Daechi High School.

Ha Neul is partnered up with Daechi High School’s biggest freak show, Kim Yi Boon. She’s a blunt and very rude teacher who already took advantage of Ha Neul’s good-heart by forcing Ha Neul to share her lesson files she’s been working on. Will Ha Neul be able to cooperate with her course partner in peace?

Ha Neul is asked to make the class materials for Yi Boon’s class. Ha Neul comes up with a novel idea of teaching students which Yi Boon cannot understand. Meanwhile, upon Sung Soon’s request, an admissions officer from Yeonhui University comes to visit Daechi High School, but he turns out to be a newbie who doesn’t know a thing about the university admissions system.

For a permanent teacher who’s coming back to the school from her vacation, one short-term teacher must leave the school. Everyone believes that it should be Ha Neul. Because of Song Young Tae, short-term teachers are in a tight spot in front of the students. Meanwhile, Soo Ho decides to track down teachers’ IP addresses to find out who posted about the corruption at Daechi High on the website.

Sung Soon is confident that she can get exclusive information about Hankuk University admissions using her connection. However, things aren’t going smoothly. Ha Neul is given an unexpected offer by Young Tae. Meanwhile, Hae Won hears that Soo Ho has been suspecting him and trying to find out his laptop IP address.

After failing to get exclusive information about HanKuk University admissions using a connection, an issue arises about the advanced class. Ha Nuel finds out that there are advantages to specific students who got to learn the curriculum in advance. Knowing that the flaws exist both in the school system and teachers, Ha Nuel decides to tell everyone about them for students. Meanwhile, Ha Neul comes across what other teachers are doing with their after-school classes.
