Inside the gym, the group is suddenly confronted by a mysterious, shadowy P.E. monster emerging from the dark corner. The monster's form flickers, with parts of a P.E. monster faintly visible.

"Whatever this is… it’s not normal. We need to follow the rule." Taehyeon said staring at the monster.

"Yeah, but what’s the rule exactly? We’re supposed to wear any part of a P.E. uniform to stay safe?" Nari said nervously.

"I only have this one piece of my top left to give… I don’t think it’s enough." you said clutching on your top nervously, you're still safe because you're wearing your P.E. pants.

"I’m not wearing anything from a P.E. uniform. Neither is Jeongwu. We’re kind of out of luck, huh." Sujin said looking at her own clothes, then at Jeongwu.
