Enemies to Survivors (BTS)

In a prestigious high school in Seoul, two rival sibling groups-the Min brothers (Yoongi, Hoseok, Jimin, Jungkook) and the Kim brothers (Jin, Namjoon, Taehyung)-dominate academics, sports, and popularity. They hate each other to the core and constantly compete.

One day, a zombie apocalypse suddenly breaks out, trapping them inside the school. Forced to
fight for survival, they must set aside their rivalry and uncover a hidden secret that connects their families. As they battle the undead and face betrayal, they realize that their greatest enemy might not be the zombies-but the truth they never knew.
