Gun Woo is rich in name but broke in reality, forced to work at his father's company for middling pay. Soon Geum is poor in name but rich in reality, with boxes and boxes of cash stashed away. It's chaos all around when the two fall for each other, as lies grow, secrets spill, and the entire neighborhood gets flipped on its head. Kim Min Joon (Damo), Min Hyo Rin (Triple), Yang Jung Ah (The Man Who Can't Get Married), and Jo Sung Ha (Sungkyunkwan Scandal) also co-star in this fresh romantic comedy about how a little lottery ticket changes hands and changes the tides of all the maids and masters of First Avenue!
