JiU heads out and finds the building where the members are being kept. She sees SuA, Siyeon, Yoohyeon, Dami and Gahyeon asleep in chairs that are assembled in a circle around a large purple crystal. She takes a look at Yoohyeon, then touches the crystal and leaves reality to save the five trapped members.

The first one that JiU finds is Yoohyeon, who is trapped in a small classroom with chairs around her. Then, she comes across SuA who is chained by her arms; Siyeon, who is stuck in a room with TVs; Dami, lying on a pile of golden coins, and Gahyeon, sitting in a red vintage chair. JiU raises the gun at Gahyeon, who just smiles at her. SuA shakes in her chains because she knew that JiU would have to sacrifice herself and she doesn’t want JiU to do that, but Gahyeon, unsuspecting, reaches out to JiU with a trusting look in her eyes. Yoohyeon, Siyeon and Dami just stare at JiU. In Gahyeon’s nightmare, Gahyeon smiles one last time before being shot by JiU.

JiU finds the other five members and herself in the meadow. Gahyeon smiles and holds out a hand, but JiU doesn’t get there in time as the five freed members fade away-at this moment, JiU realises that they have been freed but now she is trapped in the alternate world. She picks up the gun and presses it against her head, wincing. But nothing happens, and when JiU looks at the gun, she sees that she has no more bullets. She realises at this point that she did indeed free the members, but had to sacrifice herself in order to do so.

The five freed members woke in the room. All five look up at the crystal. Dami’s eyes widen and Siyeon looks away briefly. Yoohyeon and SuA gasp in shock. Gahyeon looks at the crystal. JiU, unconscious, is lying trapped in the crystal after she had saved them. Source
