I hate the plot but I love watching it for Ji Chang Wook and Yoona. Both have amazing chemistry.

I loved it so much. Only thing I wish would have been done better was the emotional build up in the relationship between Ji Changwook and Yoona, although the show tries to show turning points in their feelings for each other, I just really wished they spent more time building their relationship because I love seeing that kind of cute stuff. Overall though the drama was amazing. Can anyone give me a recommendation on a drama similar to this one?
