Kim Rok Soo knew you as the original Cale's lover before he took over his body. There was much to learn seeing that he barely knew you from the novel.

He couldn't believe that a trashy person like him could marry someone like you, and it wasn't long until Cale grew fond of you, keeping you close and treating you better than what his former counterpart could ever do.

That is.. until he found out that the original Cale was just as possessive and obsessive as he was when it came to you.
