My Twin Sister's Mate Is Now Mine

"Couldn't you just let it go? You ruined everything." My sister cried out angrily, taking off her shoes as we entered the house. "I was trying to protect you." I rolled my eyes. I should have let Aimee beat her crazy ass because she is the most ungrateful person I've ever met. "How many times have I told you to stop protecting me? I can stand up for myself, and all you ever do is ruin my life." Sideline continued to yell at me. I swallowed her words even though they killed me. "What is the noise about? shouldn't the two of you be at the party." My mom said as she and dad entered the living room, looking at us in confusion. "How could I stay there after Sienna embarrassed me in front of everybody?" Sideline cried, and of course, my parent's eyes found me, and they weren't impressed. "She was bullying you, Si, and all I did was teach her lesson." l justified my actions. I don't think I had to justify myself because she was being bullied, and I did what any sister would do in that situation, but as always, I am the bad guy, even when I'm doing something good for her. "Who did you beat?" I could tell my dad was one moment away from exploding at me. "Aimee, the Beta's daughter." Sideline said. She was definitely eager to see me in trouble. "What were you even thinking, Sienna? Aren't you tired of embarrassing me? " My dad shouted at me, but I rolled my eyes. It didn't matter what I did because I always disappointed him. "Why can't you be more like Sideline?" My mom said sighing. They were both behaving like l killed somebody. That statement definitely hit me harder than I anticipated because between them and the person that I love, I was definitely losing myself in order to fit in their description of perfection or trying to be like Sideline. "Oh, trust me, I wish I was as stupid and weak as she is." l said sarcastically, and just as I expected, Sideline started crying. I don't care what people say about me, but I can hold my own, and I don't give a f*** what anybody says about me and unlike my sister who cries about anything. "Apologize to your sister!" My dad said, and he meant business judging by the look in his eyes. If Sideline and I hadn't looked identical, then I would have come to the conclusion that I was adopted because of how they treat me. "I'm sorry for protecting you against a douchebag princess, Sideline." I spoke to my twin sister. I felt sad and helpless. If I didn't apologize, then I know my dad would make a fuss out of it, and I'm not in the mood for that nonsense. I stood up to leave because nothing good came out of us being together other than the fact that they didn't forget to point out my mistakes. My parents have always put Sideline's needs ahead of mine, and it didn't bother me much when I was younger because she was the one who got sick most of the time, but it's gotten to a point where nothing I do is ever good enough for them. They were the ones who asked me to always protect her, but they still found a way to make me feel like s*** for doing it. Just when I was about to leave, I was hit by a sharp pain all over my body. I have been in pain before, but this wasn't just any pain. Every born in my body was on fire. l screamed and fell down. "They are about to shift." Dad's distant voice said. I could hear somebody else crying and screaming in the background. l was carried out to God knows where, and the pain intensified. As the moon shined down on us, I felt like I was dying until I felt my body rearranging itself. l screamed harder than before because this was the worst pain I'd ever felt in my entire life, and I just couldn't take it. l felt my shift, and l saw my hands turn to paws before l knew it, l was standing on four feet. I could hear everything in the background. I could see everything much clearer, and I could see as far as I wanted to see, but my eyes stopped in one place. My Alpha, Arnold. I badly wanted my wolf to say he was my mate, but even though she didn't, I still wanted him. There is nothing more painful than falling in love with a man who will never feel the same way about you, but I've done it most of my life in the hope that maybe someday my feelings will be reciprocated. He stood there like he owned the place, with his green eyes narrowed at me. He has a smoldering gaze that draws anybody in. Some days, I feel like he wants me, and then he ignores me like I don't exist. Everything he does puts a smile on my face. Each one of our encounters is unforgettable, and every time he is near, I feel butterflies in my stomach. I know for sure that the feelings I have for him are of love, but most of the time, they are like a curse that weighs down on me and slowly sucks the life out of me because of his rejection to be anywhere around me. I could smell the wood pine and manly aura he emitted, and l was hooked. When he started approaching me, l couldn't help but stare at his perfectly crafted body. His muscular chest pushes against his chest. I have never seen somebody as perfect as him. With a good jawline, high cheek bone, and beyond handsome. I wish I could put my hand in his black hair and just play with it because it was just perfect and nicely done. His eyes were definitely everything to me. They made me feel naked and exposed while making me feel safe at the same time. I held my breath as he drew closer. This is the moment I've been waiting for my whole life. I just wanted him to notice me, and he was. I have always been begging for scraps of his attention, but this time, he seems to be freely giving it to me. Just when I thought he was stopping in front of me, he passed, and I followed him with my eyes, only for him to stop in front of my twin sister. l swallowed a lump that was stuck in my throat. Sideline's wolf was beyond magical. It was so brown and beautiful, and it just made me want to see what mine looked like. I saw Arnold petting my twin sister's wolf, and it made me feel like something was choking me. I wanted to break down, but I couldn't. I didn't want to make a fool out of myself in front of everybody. "Beautiful." He said to her. As she nuzzled in his hand, l felt a pit in my stomach that spread through my entire body. "I, Alpha of the Spirit Lake Pack, chose Sideline as my mate and Luna!" He announced to everyone while my heart broke into a thousand pieces. This time, it wasn't just my heart that was broken, but my soul was crushed, my ego, my self-esteem and self-worth, and every part of my body felt weak and numb. I don't know why l am not enough. I know that we haven't been close in the past 3 years, but I didn't expect him to choose my sister. I didn't care about anybody or anything, and I ran as far as I could. I ran and ran without stopping. It felt like I was carrying an entire weight of emotions around my back. My heart and body were as cold as ice. I lost half of my life loving somebody who never saw me. l shackled myself into this fate, and I don't know how to break the chains. My heart was bleeding for the love l felt. I slowed down when I felt nauseated and weak. I suddenly felt lightheaded, my vision was blurry, and everything went black.
