father i dont want to get married

i’m jubelian? the daughter of the duke and the villainess of this novel? i managed to avoid my death with some previous knowledge about my life, as this was my second time at it. now, i should be able to live a peaceful life! “i’m not going to marry a man unless he has everything. i want the most wealthy, famous, and competent man there is.” i dreamt of a glamorous life as the daughter of the duke, but my father tells me the crown prince who is known to be a lunatic is to be my husband! as an extraordinary measure, i couldn’t help but start a contract relationship. that is, with a handsome side character that looks better than the main one. “why are you trying to avoid being engaged to the prince?” “he’s scary. i heard that he even kills his own entourage if he doesn’t like them.” a few days later, the prince sent a terrible letter to me. “i will not kill you.” oh no, did i set up another death trap for myself?
