A/N: Italic words are thoughts. As their rehearsal ended, Sunny, Tiffany and Taeyeon headed back to the dorm while the others went home to grabbed their belongings.    "Ah, Taeyeon-ssi, Tiffany-ssi, Sunny-ssi. Good evening." The security guard greeted them as the three greeted him politely.   "Someone left a note for you." The security guard pulled out said note before slightly bowing, taking his leave.   "Ah, do you know who is it from?" Taeyeon asked as the security guard thought to himself.   "I'm not too sure myself but it was from a couple." The security guard excused himself as Taeyeon looked on with a confused expression.   Sunny made eye contact with Tiffany as they grinned before putting on their act.   "Another one?" Tiffany once again frowned as Taeyeon squeezed their intertwined hand.   "We'll check it when the others arrived. I'll tell them to come immediately." Sunny took out her phone and immediately messaged them.   .......

CHATROOM

  Soonkyuu: Taengoo got the note, but we have not red it yet. Manager Hwang: We're waiting for you all to come before we read it. Dancing Queen: Ohohohohoh.  Alligator Yoong: I'm on my way unnies~ KkabYul: Sica and I are on our way too. By the way, what was her reaction? SeoBaby: I was wondering too. How did Taeyeon-unnie reacted? Manager Hwang: Taetae looked confused and a little frustrated. Soonkyuu: Mmhmm.  Ice Princess: Keep the act going.  Soonkyuu: Yes, we know. Alligator Yoong: Unnie, I've arrived~ Manager Hwang: Oh okay. Taetae is going to the door now. Alligator Yoong: Okay~ KkabYul: Yah, where's Soo? Dancing Queen: Now that you mentioned it, where is this shikshin?  Long-legged Soo: I'm here~  Soonkyu: Where were you? Long-legged Soo: I was packing food for the sleepover. I'm on my way with manager-oppa. Ice Princess: Are you serious? Alligator Yoong: Soo-unnie~ Did you pack for me too?  Manager Hwang: Yah! It's not like the dorm doesn't have any food. Long-legged Soo: Yes Yoongie. I packed a lot. Fany, it won't be enough for the 9 of us. Soonkyu: It's true though. We have to shikshins here. Dancing Queen: I've arrived, Hyunnie is with me too~ Manager Hwang: Okay, I'll get the door. KkabYul: We're here too. Ah, I see you.  Long-legged Soo: I'm still about 10 minutes away. Long-legged Soo: Helloo? Long-legged Soo: Yah! Don't ignore me!   .......   Soon, all 9 of them were gathered in the dorm. Sooyoung was complaining on how the others ignored her causing them to laugh. Taeyeon was confused but she assumed that Sooyoung messaged the others who did not reply to her message.   As they settled down comfortably, Tiffany gently nudged Taeyeon to read the note while the latter complied.     Meet us at the room, near the back of the concert hall two hours before the concert starts.     That was written on the note which was passed to her by the security guard. Taeyeon froze as she red the lines again before she snapped out of it when Sooyoung snapped her fingers in front of her.   "What did it say?" Sooyoung was genuinely curious at what Taeyeon's appa and eomma wrote. Taeyeon sighed as she passed the note to them.   "Meet us at the room, near the back of the concert hall two hours before the concert starts." Hyoyeon red aloud as the others gasp in shock.   'Daebak..' Jessica thought to herself as she red the note.   'Omo. Taeng's appa and eomma sure are going all out on pranking their daughter.' Hyoyeon inwardly laughed.   "Yah! What is this?" Jessica shouted pretending to be crept out as the others stared on with 'confusion' plastered on their face.   "This is getting scarier." Sunny pretended to shiver causing Taeyeon to feel worried herself.   "Taeng, did you offended anyone lately?" Yuri asked as Taeyeon shook her head.   "I've pretty much been on good terms with everyone. Did I offended anyone?" Taeyeon frowned as she used her hands to covered her face, lost in thought.   The others made eye contact. They were wondering, was it going too far?   "Taetae." Tiffany wrapped her arms around Taeyeon's waist, in attempts to calm the girl down.   "Taeyeon-unnie, don't think too much about it." Seohyun advice as Taeyeon gave her a weak smile and nodded.   "I'm going to shower fir
