Red hair?? are you talking about Secretary Yoon? He has dark hair. The red hair is the tampon bastard cousin of ML.
Yoon is the one who’s keeping the evidences against red head. So that’s why Jiwoon and Manager Choi are giving him option to choose who Yoon wants to side with, Jiwoon or the red haired used tampon guy.
Nobody is taking advantage if you mean Jiwoon and Manager Choi are taking advantage. And I don’t even think Yoon knows that the red head boss of his is bad, because he didn’t know what the files he kept were.

I like how they"ll use the red hair secretary to get what they want from that red hair bastard but taking advantage at someone is not right so I'm 50/50 here BAHAHHAHAH pls the red hair secretary is innocent ig
