In a large, dark room, dozens of K-pop idols suddenly find themselves waking up, clad in identical sports clothes and with numbers on their backs. The tension is palpable as they try to take in their surroundings and figure out what's going on. As the reality of the situation sets in, some of them start screaming, while others quickly try to find some sort of weapon or tool. The room is eerily quiet. The tension in the air is thick, and it's clear that this is not a game to be taken lightly.
