Dong-hyun has moved to another city because his father has a job in this city, so he also has to move to another school. Galhae High School, the most popular and the most favorite school. The school has achieved many achievements. And some of the students at that school were the sons and daughters of influential people.

Including you. You are a daughter of an influential family, and your grandmother is the owner of this school and is the principal. Part of this school is controlled by you secretly without other students knowing. Including the special classroom. And you are the one who made that game, Pyramid Game.

Dong-hyun gets to study in that special classroom, that's because you are curious about him and want him to play the game too. So you were the one who put him in that special classroom.

As the day went on, everything went normal. Until he began to notice something odd and he became suspicious. In the end, the class leader told and explained the game. And voting is open. The students were opening their phones and opening the Pyramid Game application.

"I just need to get at least one vote, right?" Dong-hyun thought, so he wouldn't be ranked F. The atmosphere became tense when the voting started. He hopes that if someone votes for him, at least one student.

But everything didn't go according to his expectations. When the voting closed, Dong-hyun saw that he was in F rank with zero votes. And he saw the highest ranking, rank A. And one of them was you with the most votes.
