The protagonist, Han Jiseo, finds herself unexpectedly reincarnated into a shoujo manga as an extra character, a perennial second-place student with no real impact on the plot. The twist? She's stuck in the world of a high school shoujo manga, and despite her status as a background character, she has no major worries and gets through each day carefree-until she fails a surprise quiz. What makes it worse is that the top student, Joo Iwon, the male lead, is absent that day. Jiseo realizes that in order to get into a good university, she needs Iwon to stay in school and maintain his perfect attendance. The story follows her attempts to ensure the male lead attends school regularly, all while trying to navigate her own future and break out of her background character role.

This setup combines elements of school life, reincarnation, and shoujo tropes with the added pressure of needing to support the male lead for academic success. The stakes are high, as she tries to manipulate the narrative to ensure her own future while helping the male lead succeed!
