Chom doesn't want to and wants to be able to choose for herself who she will marry. She meets a country bumpkin named Nin and they enter into a fake marriage to prevent Chom's mother from making her marry someone else. Will this fake marriage between a hi-so girl and a country bumpkin turn into real love? And will Chom's mother finally accept Nin for her daughter?
