When I reincarnated into a game world, I was a villainess, and the heroine seems to be aiming for my fiance. Since my feelings for my fiance have cooled down, I'll break up with him and find a new fiance. That yandere villainous young master, maybe he's quite good. No, he's quite good! Volume 1 is now on sale, and the amount of content has doubled! There is book information below the table of contents, so please take a look if you'd like! Volume 2 is on sale, and the second prince appears. He's the younger brother of the crown prince. Volume 2, like Volume 1, has a happy ending and is written to be complete in one volume, so please enjoy it casually! Even Volume 1 is complete on its own, so if it's your first time, please enjoy it! A comic adaptation project is underway!
