I have been very ugly since I was a child, but I have a high IQ. My twin sister is my extreme, beautiful in appearance but a mess in studies. In the last life, my sister was unkind to others and got pregnant before marriage. And I relied on my IQ to counterattack and become the top scorer in the college entrance examination, but I was killed and dumped by my sister. In the next life, my sister was bound to the exchange system. She traded her beauty for my IQ.
