"I dont want you to forget that worry and toil are not what we are after. We should enjoy our lives." - Liu Mian Tang

this drama does not lose identity, it is consistent in tone all throughout, does not get lost in complicated plots that lead to nowhere, does not bother with unimportant characters. it knows the story it wants to tell and took time and care to tell it. the little moments are more important than the big emotional empire encompassing complications.
the female protagonist reminds her male counterpart of this while approaching the political climax of the drama. do not get lost in the trouble, focus on living a happy life. so the drama diverted to a beautiful little date, showing that happiness is found even in dire circumstances. it is a simple but powerful reminder.

needless to say, i love this drama
