"I can't promise to fix your problems, but I can promise that you won't face them alone." "Chunibyo" is the term to describe a person who manifests delusional behavior, particularly thinking that one has special powers that no other person has. As Jeongin grew out of this phase before training as an idol in Seoul, no one has ever seen his embarrassing past. However, as he enters his last year of high school, the boy meets a girl who exhibits her own signs of Chunibyo syndrome. Inspired by the anime "Love, Chunibyo & Other Delusions"
