It had never occurred to Kwon Jihyun that something like this would ever happen to her. 
Just like a loving couple, Jihyun and Mino were inseparable or so she thought they were. She believed he was the epitome of perfection. 
Showering her with gifts and constant compliments, she believed she was loved. That she was his. 

Never had it occurred to her that she was just Mino's,
Mistress.
