"Are you ready?"

Donghae blinked, fear rendering him frozen. Attached to a string at 45˚, a small ball covered with metal spikes almost touched his face, held by his y physics teacher Lee Hyukjae. 

"This will be your punishment for being late." He let go of the ball. 

Donghae wanted to hold his breath and scream. The spikes were coming towards him now. He couldn't move.

At last, after a few cycles of the pendulum, it was obvious it would never touch him. 

But his heart remained jumping around like gas particles in brownian motion.

Thump crash whiz bang /murder/.

a/n:

this chapter is lovingly dedicated to missxielan, who seemed especially determined on making one of eunhae a "y physics teacher".
