However, this system carries a profound cultural weight: the seishun (youth) narrative. Idols are expected to remain "pure," often with strict no-dating clauses. Their appeal lies not in perfection but in the effort to improve—a concept rooted in the traditional Japanese value of doryoku (perseverance). When an idol stumbles or cries on stage, it isn't a scandal; it is content. The industry thrives on the mono no aware (the bittersweet awareness of impermanence), as fans know their favorite idol will eventually "graduate" to make way for the next generation.
