Pyramid Game

Soo Ji is determined to figure out the characteristics of her classmates and the mastermind behind the Pyramid Game. She also tries to join forces with other girls who seem vulnerable. She even asks her homeroom teacher for help, only to be disappointed. Meanwhile, the 14th Pyramid Game begins, and Ja Eun, who kept skipping school, shows up.

Soo Ji begins to feel uneasy about the unfolding events, suspecting that her plan may have been compromised and that Ha Rin is catching on. Learning this, Pyo Ji Ae worries she may have made a mistake and dreads the potential consequences. Meanwhile, Soo Ji hints to Hae Jun that she holds leverage over her, coercing Hae Jun into assisting her. Soo Ji recruits a hacker to join her team.

With no Grade F in the 15th game, Soo Ji changes gears to eliminate the game with Ye Lims help. First, she suggests voting to revoke Grade A privileges and puts Ha Rin on the spot. Meanwhile, Ha Rin doesnt give in to Soo Jis hindrances and thinks of a plan to demolish Soo Jis game.

Soo Ji decides to recruit more girls to end the game and Ha Rin for good. When Da Yeon is about to be punished for what she did to Eun Jung, their teacher tells everyone that Da Yeon has to transfer to another school. Meanwhile, right before the Pyramid Game is held, Ye Lim gets taken to the hospital.

Ja Eun reveals what she used to do to Ha Rin, but Soo Ji thinks Ha Rin is just using it as an excuse to make Ja Euns life miserable. The school and Baekyeon Group decide to blame Soo Ji and her group for the violence at school, but Ms. Yoon Na Hee takes action and reveals the video of Soo Ji being bullied. Meanwhile, Soo Ji reveals the corruption behind the teacher recruitment.
