The story here is about a female that gets a job as a nanny for a rich woman's baby. This nanny is secretly having an affair with the woman's husband. At first I didn't know why but then it all came out. The nanny was out to get revenge for her brother who was almost killed in a fire in his restaurant and it was labeled an accident conveniently by the powers to be. The husband did this because he found out that his wife Ha was still seeing her ex boyfriend behind his back even though they were married. He then proceeded to cheat with the nanny I guess for revenge and Ha caught him. Here is the problem I have with this. They mention every aspect which almost puts the pieces of the puzzle together except for one thing. Did Ha really cheated on the husband or did she go there to tell her ex to leave her alone. Why would she get married if she didn't love her husband and had his child. This is why the rating was an 8 instead of a 10. No conclusive ending or complete main part of the story.
