3 girls get sent to a mansion housing 6 boys. They do some research and find out who they are. Lilith, the middle child, has recently come back from a trip to America sand sees a major difference in Lily and Rose. Rose, the oldest, thinks her sisters are childish and is pleased Lilith has better manners than before. Lily just wants to enjoy life which is not so easy when she is the youngest sister and is not always taken seriously. These 3 girls notice the guys have a secret but have still to find out. Life isn't as hard as they thought it would be living with the boys considering they lost their parents when they were 5, 4, and2and their uncle when they were 8, 7, and 5.
