At canteen,   "Krystal ah, where have you been all this morning? I can't find you anywhere in the school" Sulli asked, taking a seat in front of Krystal.   "Are you sure you've looked for me everywhere, unnie?" Krystal said, drinking her bubble tea.    Yeah, Bubble Tea. It was never a favorite for Krystal since she said its taste is weird or so. But bubble tea is Sehun's favorite so now she's drinking that every afternoon. Oh Sehun surely has a HUGE impact in her daily life.   "Of course. I've looked for you in the canteen, in the gym, in the toilet, in the office, in the park and also in the school clinic just in case you got hurt. But, duh! I can't find you anywhere"   Krystal giggled at Sulli's tiring face. "Unnie, you've missed out a place. A very common place"    Sulli narrowed her eye-brows. Thinking hard where she could possibly miss out.   "Where?" she asked after thinking for a long time.    "Library" Krystal said cheerfully.   "Library? What're you doing there?" Sulli asked in confusion.   "It's my first day for volunteering at the library. Remember?" Krystal reminded her.   "Ah..... The one that you apply for" Sulli finally understood the situation, "How did it go? Any fun episodes?"   "Good, I guess" she replied casually, "As for the fun episodes, there isn't one but instead there's an unexpected encounter"   "An unexpected encounter?" Sulli tapped her finger on the table, thinking who it would be. T
