Probably published before 2010
The two brothers always loved the girl as children but of course she was too rich for them. She always got the brothers into trouble with her father, their boss.
Something happened and the young girl has to leave her home (i think she was disowned) and she is now poor in another country, also the brothers have to leave in search of greener pastures and naturally they meet again in a different country but both their statuses is changed now
