HELP! i can't remenber the name

Hi! i'm trying to remenber the name of a drama but i can't. I remember few things:

the girl lead is a manager of an actor (male lead).

The male lead is actor but not very famous,

there is a scene where the male lead has to do over and over a scene cause the director doesn't like him and want him to abandonned the role.  The male lead is even stuck on a roof during filming and has to wait on it for the meal break.  they were filming an historical drama/movie. 

i can't remember the name of the drama and I really want to watch it again. 

Can someone help me please?  (^v^')
