4 figures come out of a room, all sweating and panting. They head their way to Yuri and Jessica’s place

“Good thing you called us out” Tiffany said

“Hey Yul, I have a trivia for you” Taeyeon called out, she’s left behind “Did you know how hot it is in that room?!”

Yuri laughed “Sorry Taeng, but thanks for the help.”

“Fany? Taeyeon, Yoona and Seohyun? They’re here too?”

“Yep. We also have part in this too you know” Tiffany said, with a smirked that appeared on her face

*Flashback*

“Come on. Let’s get this quick” Yuri instructed as she entered the train station with her friends and sister right behind her

Upon entering, Yoona and Seohyun firstly noticed that there are no people or signs of life inside; Yuri sat down at the edge of the rail, letting her feet hanging down the rails and started talking

“Im’ma get sstraight to the point guys. I’ll be standing at the middle of those rails and all you have to do is to go in that room where they operate the lights and all to push a button to change the direction of the train to the other side to save me. Push it when it turns exactly 6:10 pm, and if not, you’ll see me dead.” Yuri paused

“Why are there no people in here?” Yoona asked

“Let’s just say that I kinda rented this station. So we own this place for this time”

“Urmm I’m sure this costs a lot of money. How did you afford all of those?” Taeyeon asked, giving Yuri a suspicious look

“Yah don’t give me that look TaeTae. I got my savings you know. It came from my bank account so I did not do anything bad” Yuri assured with a smile

“Taeng unni, I really doubt if she really just came out of the hospital” Seohyun whispered to Taeyeon, which Yuri still heard
