iKon have to choose their manager because they are going to debut. However, their manager have to be nimble and handy, because they are the most awaiting group in 2015, as well as Winner, they are going to be the next "monster rookie". There were about 10 contestants, man and woman, with every background. Among of them, is a 20 years-old, Im Da-hee, who willing to do anything to get the manager job for support her family. She's clever (of course, she is already graduated from university and got cumma laude title), and very nimble. She doesn't like iKon. Ok, she's been watching the WIN and MIX&MATCH episodes for months to get to know the members, but she is not the type who wasting her time to be obsessed to any boy groups. She have been busy studying and taking part time jobs, she thinks. But working on YG entertainment, with those atmosphere and great salary, she is going to make her attach to the group, no matter what.

But, what happen if she's finally fall in love with one of the member? Will it be a massive danger? for her career and his career?
