Jung Daeman leads a double life. On the outside, he’s the adopted son of a rich and beautiful family, but behind closed doors he’s little more than their servant. Only one of his “sisters” is ever nice to him, and the rest of them work him like a dog! Things only start to change when the head of the house, Mr. Kim, comes back from a business trip, and makes it clear that he thinks of Daeman as his son and tells his wife and daughters to be nicer to Daeman. The thing is, while he might want them all to be closer, surely he didn’t mean this close?!
