Highest ranks: #3 in sachaeng. Everyone wishes to be rich. Except for Son Chaeyoung who hates the fact that he is a wealthy young man. Why? It's because of his greedy father who prefers money over EVERYTHING and EVERYONE. Chaeyoung and sana will meet and he will live with her as a GAY guest in her house. Will he get caught? Will she fall for him? Will they be able to face the ups and downs?
