id rather abandon you than be abandoned

Read manhwa I'd Rather Abandon You Than Be Abandoned / I Would Rather Abandon You Than Be Abandoned / I'd Rather Abandon Than Be Abandoned / I found myself embodied in an otome game. The problem is that I am not the heroine, Nyla, but the villain, Claudia. Naturally, Claudia's social reputation is at rock bottom. My brother himself despises me, and my fianc treats me like a stalker. In this case, I will be unjustly executed by guillotine for crimes I did not commit. So, in a desperate move, I propose a contractual marriage to the Cursed Prince to get his help, but he takes his role as my husband too seriously! Additionally, the original heroine, Nyla, who I thought was good, seems suspicious. Why are you trying so hard to portray me as an evil character? Was Claudia really as bad as everyone thought?
