Min-jun and Seo-ah have the opportunity to take part in a simple game, win big and all they have to do is - fall in love? To Seo-ah, it was ridiculous but that prize money is nonetheless life-changing. She would be able to take care of her family and even get into her dream graduate school. For Min-jun, that money can simply pay off her debt, that's the only reason she is here once more. There's nothing else to say. It's a gameshow and one can easily play the system. "It's pretty simple isn it? After all, you two were once lovers."
