He was busy bullying some boy called Sunggyu and she? Well she was just being distracted watching her ex from afar, Kim Junsu, in her eyes he was almost perfect and she was sure they would soon be back together. Baekhyun lifted Sunggyu's book and waved it, so the helpless nerd wouldn't be able to reach it, the boy tiptoed in vain, the heavy book slipped throught Beakhyun's fingers and landed on top of  Taeyeon's head, so the dwarf finally woke up from her dream land. "Auch! What the?!" she yelled and looked up just to find Baekhyun trying to hide himself while Sunggyu vanished only saying "Good luck!" Baekhyun thought of how weird it sounded. It's just a small girl, what could actually happen?
