Her swearing is irrelevant because the person she hates did no wrong to her.Infact,she is the one who slaughtered the man into pieces to use his parts to cure the man she claimed to love ,whom is married to other woman. The thing is that the drama failed to give the audience details of how SuYing fell in love so hard for the man even when they showed her lack of interest in the same man.Then again the fail to show us how the dragon met SuYing and fall in love with her.😮.Sometimes, the script writers go off charts as if the drama is not watched by intelligent people.
Exactly,all dragon King did was love her but she deceived him, never truely love her , only wanted to kill him and take his powers and scale to give the one she truely loved,who by the way rejected her,she is wicked and evil , she tore her own life apart,and her word to dragon King for me is rubbish, he very try to hurt her in the fist place,so how can her curse affects him.
