Exchange Student (DenNor)

Hello! I'm continuing where the I-Am-The-Only-Norway left off (with their permission, of course!).
As you recall, Lukas is a student at a public school chosen to be an exchange student in Denmark. He lives with his younger brother Emil, their mother, and their drunk of a father. He has been working since he was 12 and wishes his parents would divorce for the sake of his mother. Mathias is the child of a famous inventor, and has been lonely his whole life, for his mother died at child birth. He and his father live in a large mansion. How do these to meet you ask? Lukas's host family happens to have the last name Kohler. :)
