Once, I was called a villainess, had my engagement broken off, and was condemned. Now at 28 years old and single, I work as a shop attendant (older sister type) at the magic academy's purchasing department, yet for some reason, a student has confessed their love to me.

I am a former villainess who was engaged to a commoner named Marianne and sentenced for attempting to push her down the stairs and kill her. Now, about 13 years have passed since then. I was sent to the frontier, drifted to a neighboring country, and for some reason, I now work as a clerk at the magic academy's shop. Having become emotionally numb to romance, I remain unmarried. I spent my days finding comfort in Chris, who visits every day... but then one day, Chris handed me an invitation, saying there was a ball being held by the Crown Prince and asking me to attend. When I went to the ball, an engagement partner was announced there, but who was it...?
