Who is the Housemaid?

I liked the story, it gives people hope. The unfortunate part of this movie is that it is somewhat predictable (Will not give out spoilers)
Who is the housemaid? Us non-chinese speakers/readers need to have her name. She is the co-star and we have no way to know who she is ?!?!?!
So, MyDramalist: Please get a Chinese speaker to write the name of the housemaid character's actress name. She is young, so she won't have many past credits to her name.
Watch it for a light love story. Don't watch it if you're looking for a high budget film.
