About
Every last Thursday of the month at an all-girls high school, the students of Class 2–5 cast their votes in a popularity poll. The results classify them into Grades A, B, C, D, and F. If they fall into Grade F, they become legitimate victims of school violence.

Sung Soo Ji: The Transfer Student
Soo Ji transfers to Baekyeon Girls’ High School and discovers that her class plays a game called the Pyramid Game in which the students decide on a hierarchy based on a popular vote. As Soo Ji ends up in the lowest rank, she devises a plan to get back on her feet.
The Mastermind of the 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.
The Birth of a Trio
Soo Ji moves up to Grade C, and the treatment she gets changed completely overnight. She breaks the promise she made with Ja Eun, but she decides to join hands with her and help the new girl in Grade F, Pyo Ji Ae. Soo Ji, Ja Eun, and Ji Ae come up with a plan to destroy the pyramid altogether.
The Leaked Plan
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.
Parent Observation Day
During the parents' visit to the school, Soo Ji gets caught up in Ha Rin's trap. While Soo Ji tries to make a pact with Do Ah, Seung Yi puts on a show to put Soo Ji on the spot. Although the parents witness the ordeal, Ha Rin turns the situation to her advantage and even has her grandmother, the chairwoman of Baekyeon Group. Meanwhile, Soo Ji switches to her Plan B.
Tables Turned
With no Grade F in the 15th game, Soo Ji changes gears to eliminate the game with Ye Lim's help. First, she suggests voting to revoke Grade A privileges and puts Ha Rin on the spot. Meanwhile, Ha Rin doesn't give in to Soo Ji's hindrances and thinks of a plan to demolish Soo Ji's game.
Shattering Friendship
Baekyeon Girls’ High School goes on a school retreat. While practicing diving, someone pushes Ha Rin into the water, and Ja Yeon jumps in to save her. The next day, Class Five plays a survival game using paint guns. The last five standing, Soo Ji, Ja Eun, Jae Hyung, Eun Jung, and Ji Ae are put in danger of ending up in Grade F.
The Majority
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.
