-Aerin’s POV-   Yay! No eighth period again. It was just what I needed – rest. I packed my things and spent my time sorting out the books in my locker. I needed to bring home some of them and I stuffed the things I needed into a duffle bag so I would just have to grab it when I was about to go home. I was in the middle of clearing some papers I didn’t need, stuffing them inside a small trash bag when something fell from in between the stacks. I saw that it was a yellow envelope with something scrawled on it. I bent down to pick it up and read the writings on it. It was barely understandable. Whoever wrote it wrote with his or her feet. I was able to make out my name on it.   “What the hell?” I didn’t notice before that my name was something hard to spell. The person who wrote it spelled my name ‘Kwon Ehrin’. How stupid is that. I was chuckling to myself as I opened the envelope. A small sticky note was inside. It read:   GIRLS' BATHROOM. NOW!   Maybe it was Sehun trying to annoy me again. I stuffed it in the trash bag along with the papers then placed the bag in the nearest trash bin I saw after slamming my locker shut. After that, I went to the girls’ lavatory to see what he was up to again, but when I got there, I didn’t find him there. Instead, a guy from the Gen Ed class popped out of nowhere and slammed me against the cubicle door, grabbing my neck tightly.   “Yah!” I shouted at him, my voice bouncing off against the walls.   The guy stared at me intensely, tightening his grip on my arm and neck. He didn’t bother to secure my injured hand. “Shut up!” he growled.   I glared back at him. “Unhand me.”   “Or else what?” His grip on my neck tightened even more and I could feel myself becoming nauseous.   “I don’t give a damn what you have to say. Let go!” I retorted, struggling around the small space between us. I was mapping out my plan to ward him off, but I could barely think of something.   “Listen and listen well,” he began. “Stay away from Park Chan Yeol.”   I managed to push him back and he ended up bumping his lower back on the sink. “You’re letting that y blond treat you like her little pushover? What are you, her frustrated lover?” I said sarcastically, sneering at him.   “You’ve got a lot of guts telling me that.” he grabbed my arm again and slammed me against the door. Damn, that hurt! I felt myself losing breath. “Heed my warning or it wouldn’t be pretty for you.”   “Tell your alpha dog to bring it on. I don’t give a , you !” I mocked him with my stare then kicked him on his crotch. That sent him howling in pain as he bent down to clutch the spot. When he regained composure, he limped towards me, motioning to pull me down. It was a good thing that I was quick enough to react to that. I used my injured hand to crush his nose. I felt the bone underneath his skin snap and it bled like my nose did when Sehun tripped me some weeks ago. He backed away from me and ran out of the bathroom after that. That was a close call. I felt my knees buckling after that and I just resorted to settling down there, steadying myself, catching my breath.     -Sehun’s POV-   I passed by the girls’ bathroom that afternoon and saw Aerin sitting on the tiled surface of the sink. I stopped by the door and saw her wincing as she removed the bandages that stuck on the wounds of her hand. A train of curses followed after she pulled one so suddenly and she looked like she was going to punch the wall with the same hand again. Confused, I watched her quietly. She seemed to be in a better mood the whole day. I wonder what happened to her again to make her so agitated. She leaned on the sink as she stood down, staring at herself in the mirror as she gripped the sink. Aerin tossed the soiled bandages against the mirror, breathing laboriously. She bowed her head down, muttering unintelligible words. It was like walking into a sleeping bear’s cave and accidentally rousing it.   “What are you looking at?” she snarled. I didn’t notice that she was looking at me through the mirror.   I marched in and took her hand. “What’s the matter?” I asked, matching her tone. It was one thing seeing her get hit on the face, but it was an insane scene seeing her deteriorate right after that.   She shook under my touch as I steadied her. She looked as pale as ever. “I’ve had enough,” she murmured, resting her forehead on my chest.   I hugged her with one arm. “It’s Eunmi.”   She nodded against me.    “What did she do?”   Aerin slowly straightened up, pulling her hair to one side to show me her neck. Reddish marks that resembled someone’s hand were starting to bruise again. I felt rage welling up from inside me and I knew I didn’t have the patience to let it slip just like that. I glared at the marks, taking her by the shoulders. “Did she do this to you?”   Her eyes became hazy as she shook her head. “She couldn’t have even if she wanted to. She sent someone else to do it. He’s a senior, I guess.”   He? A guy did this to her? The rage I felt turned into an instinctive bloodlust as I ran a finger through it. “When did this happen?”   “Just now. I tried to fight him off, but it was quite futile. Injured hand, remember?” She raised her hand to show me. I guess she used it again. It’s swelling more than it should. She chuckled bitterly, putting her hand over mine on her neck. “If I get expelled on Monday, you know why, alright?”   Her words made my temper rise even more. Why was she being so hard-headed? “No,” I said then went out of the bathroom to find Bae Eunmi. I scanned the hallways and found her at her usual spot with her friends. She immediate
