"Sara, it would be sara. That is why I made sure to tell her not to make any contact with cha min-geun, and I know she won't disobey me. That is why we need to contact her before she reaches his office."
"....Okay, uhmm well, I do not know about her disobeying you or not, but what I do know is, it doesn't matter if she speaks to Mr cha or not."
"I don't understand, if she gets to him, she will tell him everything she heard."
"I know."
"And our plan will be sabotaged."
"Exactly."
"Can you please explain to me what is going on!?"
Da-hee pauses for a while and then she responds. "I believe that art imitates life, and when you watch a movie, it's almost always separated into three parts, the beginning slash introduction, the climax slash betrayal or revelation, and lastly the end slash redemption. Whenever I explained my plan; what did I always say?"
"The plan is too easy."
Hearing tae-hyun's response made da-hee smile a bit, she was glad he understood her; and then she responded. "Exactly, we need an obstacle, a betrayal, and besides Mr cha already knows about our plans."
"What!?"
"Of cause he did. He is a smart man that has eluded a lot of people. He wouldn't be where he is if he were dumb. He has people watching me and my sister all the time. He probably has pictures of you coming to my apartment, of me going to your house that time and of me going to your office building so late at night. What reason could I have for coming here so late at night."
"My goodness."
"The mans paranoid and he doesn't trust me for obvious reasons."
"So what do we do now?"
"Mr cha needs to believe that we are in his hands, and when he does, all fear and paranoia shall disappear and then what would be left is a very prideful man. That is how we win."
(Now to present time.)
"Now shouldn't you go confront your wife for betraying you? Do not worry I will hand the documents to the authorities."
"Be careful da-hee." Tae-hyun says to her as he leaves his office.
