Help me find a kdrama with a aspiring drama director fl

She initially maybe noob kinda assistant but she laters gets to film a drama full by herself. I dont remeber if its a miniseries or long drama with 50 kinda eps. it has winter vibes. 

This was the only drama i watched where they show full in detail her filming the drama as the director. IDK it might be she overtook as one of directors, like it seemed there were two teams, and she was one of the teams. So there was maybe one more director working on the drama.
