I was rejected based on my appearance, so what?

"A harsh appearance"――for that reason alone, Marquis' daughter Seraphina was abandoned in public by her fiancé, the prince. Her replacement is a rival lady who is angelic in appearance (but corrupt at heart). However, Seraphina remains unfazed. "...So?"

Waiting there is Gideon, the captain of the knight order, rumored to be rough-mannered and disdainful of nobility. Yet he sees through Seraphina's sharp, striking appearance to perceive the remarkable talents and deep kindness hidden within her. Meanwhile, the princes in the royal capital who abandoned Seraphina seem to be making one blunder after another...?
