The young lady who broke off her engagement stopped being patient

The Crown Prince, who became his fiancée, fell in love with his younger sister, who was as pretty and adorable as a fairy.
Although she doesn’t remember when she died, Faustina somehow regained her memories of the previous engagement on the day she was engaged to the Crown Prince, and this time she stopped holding back, determined not to fail.
This time, the Crown Prince gave up and handed over to his younger sister, and did what he wanted.

All of his attempts to break off the engagement were in vain, and different things happened than last time… It seems that things aren’t going to be easy.
