Let There Be Selection!

I never believed in fairy tales, magic, or other nonsense. But my fiancé betrayed me with my friend, and her abnormal grandmother promised to send me to the next world. And indeed—I ended up… in another world, swapping bodies with a student of a magical academy! In this world there are dragons, witches walk around, and the local ruler holds a selection of brides for himself and his sons. What do I have to do with this? Oh, I’m already a fiancée? Well, we’ll see!
