The story of two girls separated by oceans began at their birth, when their mother and father could not care for them and put to two young children up for adoption. One daughter was adopted by a young couple in Germany, and the other by a couple in their mid twenties residing in America. 

The two knew nothing of each other until fate managed to toss the two together. 

However, in the attempt to find their past, understand why they were separated and taken from their birth parents, the two girls meet a rag tag group of odd boys who go by the name of BTS.
