Serra is a normal senior high school student who works really hard every night and weekend to pay off her parents' debts from loan sharks. But when she couldn't keep up with payments anymore, she decided to end her life. Surprisingly, she woke up in a different light-- in another world. What's more shocking was when she is addressed by one of the people as the demon king's bride.

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!

My lazy stepbrother, Derek Lane, suddenly becomes the hardest-working person in the village. He cuts weeds, carries buckets of manure, and works the fields. Nothing seems too difficult for him. But while he works, cuts suddenly appear on my hands. The carrying pole rubs my shoulders raw. Even the soles of my feet split open. I have no idea what kind of dark magic he uses, but every injury he suffers is somehow transferred onto me. After spending an entire day laboring under the blazing sun, he remains full of energy. Meanwhile, I collapse from heatstroke. I tell Dad to stop Derek from working in the fields. Instead of listening to me, Dad drags me to the village square and publicly lambasts me in front of all the villagers. He scolds, "You still think you're some spoiled boy who came from the city? Not only are you too lazy to work, but you're even spreading lies that Derek is using black magic!" From that day on, Derek works even harder. But at the same time, I can no longer work in the fields at all with my body covered in injuries. A week later, he's named the village's "Farmer of the Year". Thanks to that title, he earns the chance to head to the city and attend college. As for me, I collapse from exhaustion and die in the cornfield. Wild dogs feed on my remains. When I open my eyes again, I'm back to the first day Derek is trying to steal my work points. There are 15 days left until the fall harvest. I have 15 days until I die in that cornfield. I snatch the carrying pole from Derek's hands and say, "I'll handle my own work."

To cure my half-sister's illness, my brother took my beast bone—all because I was a half-beast and had a strong self-healing ability. Later, to make me suffer in her place, the tiger beast servant I had cared for joined forces with my brother and sent me straight into the Beast Den. The tiger said I didn't deserve to be his master, and the one he wanted to protect was my sister. In the end, I was tortured and died a terrible death. When I opened my eyes again, I was back on the very day I had to choose my beast servant.
