Krystal headed towards the Science section, ready to end her unfinished work yesterday. But she saw someone sorting the books on the side-table. Since he's back-facing her, she couldn't see his face but somehow she felt very familiar with the back.    She knocked on the book-shelf to catch his attention and quickly bowed as an apologize for not finishing her own work.   "Thank you for finishing off my work and I'm sorry for making you more busy" she said, still with her head down.   "Ermm... It's okay. We should have done it together yesterday but I had extra classes so that I couldn't join you" he also said his apologies and bowed.   That's when he saw her face, covered beneath her wavy hair.   "Krystal shi?" he said, more like a question.   Her head shot up when she heard the voice. A gentle yet attractive voice. And a voice she wanted to hear the least for today.   "Sehun shi?" she asked, obviously surprised since she never saw him in the library on the other day.       There, they stared at each other, giving a questioning look.

Why won't you wait for about 7-8 mins? I'll finish them off in a lightning speed"    "Neh, oppa. So I'll be waiting there" she said, pointing to the desk near the window.       Krystal finally spoke up after Hayoung walked out.   "Sehun shi, why won't you go with the others to play basketball? I'll finish it up on my own" Krystal suggested.   "Aniya!" he refused, "I should finish it
