Hotel King remembers me That Winter the Wind Blows in many ways. They have similar storylines based on power struggles. Both female leads are orphan heiresses, and both man leads wanted at first to take advantage of them before falling for them. In both dramas, one of the two main protagonists believes the other to be his/her sibling.

They also share the same atmosphere, I felt the same way watching those shows, with all the background manipulations and the constant danger threatening the main protagonists. Both hook you in a way that you can't resist the envy to watch the next episode.

I really think that people who enjoyed Hotel King will enjoy That Winter the Wind Blows. The main actors are really good. The main actress did a great job at playing someone blind. I love her character, who, despite her blindness, has a real willpower and does everything to stay strong.
Moreover, this drama does have something really poetic, and is esthetically really beautiful to watch.
