The Ill-Fated Lady Is Oblivious to the Elite Sorcerer's Obsessive Love

Liselotte Clarence, daughter of Count Clarence, has been set to marry the Frost Adelgrant of the Marquis's family... but she has despised him since they were just children. After years without seeing one another, it seemed as if Frost might have changed for the better- but in only an instant it was clear that the same rude, distasteful boy had not changed in the slightest. Liselotte's had enough of it all. With one loud yell the engagement was called off and she left her home in a rush. After all things were settled, she now finds herself working for a magic tools shop and meets another young man named Snow, but something about him seems familiar...?
