I was called plain-faced and glasses-wearing, and was framed by my beautiful sister, the most beautiful woman in the country, resulting in my engagement being broken off. Do men only look at women's faces...? Then I'll use this method to take my revenge.

I'm a plain girl with glasses who was told, "I don't want to be engaged to someone as plain as you—I've found my true love." I was about to be exiled to the frontier for bullying the sister of my true love's new partner, so I fled and sought help from my cousin in another country while planning revenge. However, this cousin of mine is a rather unusual person.
