sowon was the first one to regain conciousness. she forced herself to get up, while her head was still dizzy. everything felt like a fever dream⏤ an unfamiliar surroundings, flickering lights, and spooky noises coming from nowhere. "guys? guys, get up!" sowon looked around, panicking as she saw the members lying on the ground. five girls were together on a journey to find their true selves when they got hit by a sudden storm and adrifted into a strange cave. hearing sowon's call, the others struggled to get up and glanced around cluelessly. after a while, sana opened her mouth trying to say something as a sudden blue lit of fire coming from the end of the cave caught everyone's attention. "what on earth could that be?" zoe's voice trembled. not a single reply was heard⏤ no one has ever seen something like that before. a chill crept up their spine as the flame grew bigger and closer. then suddenly, a deep and mysterious voice echoed throughout the cave. "once you have gotten here, there is no way out." hearing that, the girls looked at each other horrifiedly. the voice continued⏤ "unless..." "what are we supposed to do?" haru, the only one to remain calm, deliberately asked. sowon grabbed her hand and held it tightly, not wanting anything unfortunate to happen. "unless, you found the owner of the cave." it whispered and slowly faded away into the air. a wave of creep surrounded the atmosphere. finally, sana broke the silence and said: "that means someone else apart from us is in the cave at the moment." mimi nodded in agreement. "and all we have to do is to explore the cave and find out who they are." "let's go. we can get through this." sowon said decisively. five girls, five souls, one spirit. will they be able to return?
