A popular online game's rank one player, JjamppongSundubuRamen, is a high school girl—Seongah Myung. She wants to keep her status as a ranker a secret from everyone around her, but on her first day of high school, she meets Hanjun Kang, the player behind StrongJun, someone she has a bad in-game history with.

While agonizing over whether she should drop out of school, fearful that her identity may be discovered by Hanjun Kang, standing before her is Taeui Ahn, who looks exactly like her in-game character, and Seongah falls in love at first sight.
