I grabbed my metal water bottle, slammed my locker shut, and walked into the locker room's adjoining bathroom, grabbing a small towel as I passed the supply rack.  I wiped my forehead and neck with the towel and then soaked it under the faucet before pressing it to my face.  After several long seconds, I rung out the towel and filled the water bottle from the tap.  I had long grown accustomed to its slight metallic aftertaste.     I hadn't realized exactly how thirsty I was until I had started drinking, and within a few seconds I was holding an empty bottle to my lips.  Setting the empty bottle on the counter by the sink, I stared at myself in the mirror.  I was not one to admit it to anyone but myself, but even I was intimidated by Taeyang.  But, of course I should be; he took his Supplements, which amplified his already bully-like personality, and he was a quick learner when it came to combat training.  I refilled my water bottle and threw the wet towel into the laundry shoot as I walked back into the locker room.     Seunghyun and Jiyong were waiting for me outside of the locker room hallway.  "Are you okay?"
