I, The Female Lead, Ruined The Original

I had the role of a female protagonist. But there’s a problem…. “When women get together, dishes get broken, so be careful on your own.” “Oh, really?” This world was from a spicy adult novel. And the male lead is oddly individualistic? But he’s a prince, so there’s no alternative? Well… I was born with a diamond spoon. I planned a comfortable life. But suddenly I heard two incredible words. “Chicken and beer.” …Chi- what? As it turned out, I wasn’t the only one who had transmigrated to this place. There’s – A noble in the Imperial Guild, A fake royal princess collecting escape funds, A regretful man X who finds solace in the temple and, A maid escaping a reverse harem. But why isn’t there a handsome, high-ranking man who can get along with me and twist my original story? Unfortunately, my friends are either enjoying twisting their own story or waiting for my original story to begin… In order to find the last member of the “Possessors’ Club,” a masquerade ball was held. And then a man appeared who had the perfect mix of my preferences! A black-haired, cold and beautiful man, and on top of that, he’s my ultimate fan. “Excuse me, would you like to chat?” “Well, I came here because I was curious about Miss Leah.” I thought I would have a lively conversation while enjoying his satisfying face, even if I didn’t get to eat him. I was sure that was the case… “Damn it.” It’s ruined. I, the female lead, had screwed up. Shouldn’t I have refrained from spending the night with another man?
