I Overdid the Adopted Daughter's Role

When I first entered the book, my goal was simply to survive. As thin, long, and happy as possible! That's why I did my best to live. I was about to become independent and walk the flower path, but... "No matter where you go, the spot next to the master is mine. We promised to stroke each other's hair for life, didn't we?" The strongest male lead, who was supposed to be stabbed to death in the original story, stared at me with obsessive eyes. If I said no, it felt like I would destroy the world. "Yeah, I'll kill him. Then you'll be happy, right?" My fifth older brother seems quite insane. "From here to here is my land. And it's yours too. I'm glad I can breathe with your great dreams." My fourth older sister, who became the richest person on the continent, spread out a map and said this. If I said I didn't have such great dreams, it felt like a great disaster would happen. "I'm so looking forward to the Winter Castle that the Lady will fully govern." A smile bloomed on the face of the butler who served me. "If you don't succeed Bella, my heart will stop tomorrow morning. Is that okay?" My eldest sister, who should have become the heir, threatened me with her life. And this was the biggest problem. For some reason, my father, who had become even stronger than in the original story, had a grim smile on his lips. "Independence? Go ahead. I won't leave a single ant alive in that land." Do you think you can leave my arms and become independent...? He glared at me with ferocious eyes. Something's wrong. Something's gone very wrong. I just did my best.
