Contract marriage or a drama where fl is a high ranking person and the ml is lowly ranked

is there even setting like this? It is always a man who is prince/rich CEO/person of importance while female lead is normal/poor/commoner. 

the only one i can think of is The Beauty Inside where FL is a top actress but ML is still a CEO
