Why Did The MC Get An F-Class In 'Beastman Prefers My Sister'?

In my previous life, my parents doted on my frail, sickly younger sister. For her sake, they chose a hawk beastman willing to settle in a human city as her husband. Me? They cast me into the deep sea, marrying me off to a giant shark beastman. When the apocalypse came and torrential rains drowned every human city, my parents and sister were left clinging to a rotting plank, adrift on the endless ocean. I couldn't bear to watch them die. With my giant shark husband, I dragged them down into the deep sea to safety. But resentment festered. Seeing me live comfortably while my shark beastman hunted day after day, my parents grew furious that my sister's life paled in comparison to mine. In their jealousy, they laced the fish we ate with poison and killed me. Now, given another chance at life, they've decided my sister should marry the giant shark beastman instead. My biased parents believe she will finally enjoy the blessings they once denied her. But what they don't know is this: after the cataclysm, fish become scarce. And a giant shark… does not survive on scraps. He needs flesh.

I was the daughter of the Ashford Pack Alpha — the most beautiful she-wolf in the entire southern territory. Alphas lined up to pursue me, and I couldn't be bothered to give any of them a second glance. Until my best friend dared me: "Sera, I've got a bet for you. Think you can make my brother Kieran fall for you? Win, and I'll give you my mother's healing moonstone necklace. Lose, and you hand over that limited-edition sports car you love so much." Countless beautiful she-wolves had tried to get into his bed. Every last one of them had been turned away cold. The very first night after I took the bet, I saved Kieran from a silver poisoning, and spent the rest of that night tangled up with him while he burned through his heat. For the two years that followed, he grew more and more obsessed with me. On the long conference table in the pack meeting room, he pinned me down against the papers. In every room of his private estate, we left traces of ourselves behind. I gradually fell in love with him during countless intimate moments. Until the night only to overhear his conversation with the pack elder. "Alpha, it's time to announce who will be Luna." The Elder's voice was low and deliberate. "Miss Seraphina has been by your side for two years now. According to pack tradition—" "Enough." Kieran cut him off. "She and I were just having fun." The Elder was quiet for a moment. "And your first love? When you two separated, she asked for two years apart to try other partners. Those two years are up now. Isn't it time for her to come back?" "Yes." Warmth finally crept into Kieran's voice. "It's time for her to come back." That was when I realized — his so-called true love was my half-sister. The person I hated most in the world. For two years, I had been just his experiment while he "tried someone else". I turned and walked away without a second thought. But this powerful Alpha went mad — tearing through the entire wolf world searching for me.

"I know you're an ace divorce attorney. Please help me!" A young woman who's holding a child suddenly barges into the law firm and gets down on her knees in front of me. I'm about to help her up to her feet when a few live comments appear in front of my eyes. "This really is a doomed story. I can't believe the FMC has to go through all sorts of torment before dying." "Once she gets caught, both she and her child will be dead. The MMC can only spend the rest of his life in eternal remorse." "The FMC is pretty naive, isn't she? She thinks finding herself an attorney can help her secure a divorce. The MMC is the richest man in Opalford at the end of the day, so there's no way she can file for a divorce successfully." When I spot the next comment, its contents sting my eyes immediately. "Unfortunately, this attorney is a throwaway character too. Not only does she refuse to help FMC, but she also fails to recognize her as her older sister, who has gone missing for many years."

My older sister, Noelle Brown, has an unhealthy obsession with me. When I was ten years old, Noelle almost got kidnapped by the kidnappers. I got into the kidnappers' van in her stead. Later on, I was returned to my family after they paid a ransom. But my face had already been slashed by the kidnappers, and my legs had been broken by them, too. Since then, Noelle has worked extremely hard to improve herself. That's how she successfully brings the company Dad has left behind to a new level of success. I become Noelle's most cherished person as well as the vulnerable spot that no one else is allowed to touch. Someone made fun of my ugly looks in the past. Noelle had stuffed his head into a sack filled with rats, where he literally got his face chewed off him alive. There was also someone who ran his mouth about me being a cripple behind my back. Noelle responded by crushing his legs with a road roller, resulting in his legs being reduced to paste. Noelle is the demoness who's feared by the entire city. But to think that such a fearsome woman dotes on me endlessly. She even dumps a huge amount of money into sending me overseas, where I undergo numerous plastic and orthopedic surgeries while finishing my college studies. Before returning to the country, I receive an engagement invitation from Noelle. She tells me that soon, I'll have a brother-in-law who will spoil me like she does. She even sends me a photo of her fiance, Faris Smith. But as soon as I arrive at the villa, Faris barges in with a group of brutes. He's mistaken me for Noelle's side piece, whom she keeps in another country, so he begins torturing me endlessly. By the time Noelle reaches the scene, Faris points at me while shouting at her. "Don't tell me I can't even compare to that pretty boy!" Noelle's eyes go bloodshot at the sight. "What makes you think you're even worthy of being compared to him?"

Damian, my destined partner, is the alpha that all wolf girls dream of. For him, I went alone to the North, his pack. But for three years after we signed the contract, he remained chaste, staying at least three feet away from me, refusing to mate with me. I thought he was just busy with the affairs of the wolf pack and had no time to care about me. Until I stumbled upon Damian pinning Lyra, his sister, against a rough tree trunk, his mouth savagely devouring her lips like a wild beast. "You know I long for you, Lyra!" he roared. "Why did you force that boring Selena on me?!" At last I understood. The only person he truly loved was Lyra. He hurt me again and again for Lyra, and even when we were trapped in the forest and almost swallowed by the shadow plague, he ran away with Lyra in his arms without looking back. "Whether Selena can escape or not has nothing to do with me. You are the most important person in my world!" I was heartbroken, but he wanted to complete the final mark with me because of guilt. He didn't know that I had already dripped my heart's blood on the moonstone the day I found out about his affair with Lyra. Our mate bond had been completely broken long ago.

After the human race loses the war, the beastfolk rule over the human lands. As crown princess, my sister Amber Whitaker is born beautiful and is handed over to the Beast King, Theron Olson, as his concubine. Compared to her, I'm plain, so they send me to the breeding quarters, where beastmen fight over me and use me like a breeding machine. However, Amber doesn't fare well either. She's too gentle for palace schemes. Before long, the other women frame her, and she dies. As for me, pregnancy after pregnancy wears my body down until it's too weak to go on, and I die filled with hatred. Then, everything blurs. When Amber and I open our eyes, we stare at each other in shock and realize we're back on the very day the human race falls. This time, I hold her hand tightly and say firmly, "Let me serve the Beast King instead!" On the night, Theron takes me to his bed. "You look so slim, yet you're surprisingly full. Are you afraid?" With that, he strips away my clothes and casts off his own. One glance makes my breath hitch. I've seen beastmen's packages before, but I never expected Theron to have two!
