The sudden nasty-sounding thump made Melissa sit up just a little straighter in her chair.  What was that?  She only barely heard it, and fortunately she'd taken her headphones off or she wouldn't have noticed at all.  Jumping from her chair, she dashed down the corridor to find out.<br/><br/>As soon as she threw open the door, it didn't take her long to recognize the problem.  "Oh, Miyu..."  She ran over to the bookcase, wrapping both arms around it and trying to give it a sharp heave.  "...Ugh..."  She wasn't quite strong enough, but shock mixed in with desperation to try to give it a solid go anyway.<br/><br/>No good.  She could try yelling, but in this room, even with the door open, people weren't likely to hear.  "I'll be right back," she said to Miyu, instead running down the hall to the staircase for a proper yell.  "Hey!  Everyone come and help; Miyu got her leg stuck!"
