How about the president who groomed Ha Jin to be the way he is and Ha Jin who made Si Yeon the fucked up bitch she is?
How did Ha Jin make her a fucked up bitch? Are we forgetting that she doesn't and didn't know what he did for a living- he didn't bring work home nor did he get her involve in anyway. She made chicken boy follow him. She was caught having an affair by red hair girl. It was both her and red hair girl actions (red hair girl kidnapping ha jin and her being away with chicken boy) that made the president think she and ha jin ran away together. Don't get me wrong, i am not saying that Ha Jin is innocent, but to me, Si Yeon played a bigger part in their current predicament plus we don't really know the back story of how they got together so we can't really say "he got her on the organization radar in the first place".
Si Yeon was also willing to be fucked to find Ha Jin in the earlier chapters and she's also the one who got chicken boy to sneak into the company
To think that the most fucked up and manipulative person right now is the horny cheating slut airhead in the beginning. The moment Hajin woke up, she immediately pretended not to know Chicken Boy, as if he was part of the organization. Her other self is mostly the manipulative one, but it's a part of her nonetheless. She planned everything.
