both, just watch both!

Director's work. Must watch for the cinematography, directing, editing, poetry, arts, romance, life and Lee YoungAe and Song Seung Heon's magical chemistry.

Both are affair dramas except for this main reason: THE CHARACTERS ARE TOTAL OPPOSITE. The more you watch them, the more you understand them, the more you reflect about life. Actually, it is not a cheating drama for me. Rather a healing romance drama about four people entangled in a dangerous web just to show people that LIFE IS THIS SWEET. After watching, it will make you ask yourself, "How are you, my sanity? Stop messing my thoughts about life and love." My all-time favorite Korean Drama. No one beat it yet.

The director of the drama is the same (Yoon Sang Ho) only the set up is set on 1930s of South Korea. Some actors like Lee Hae Young (his breakthrough performance), Kim Bup Rae are also in the drama. This is the Independence Commemorative Drama of Korea back in 2019 starring award winning actors Lee Yo Won, Yoo Ji Tae, Im Ju Hwan and Nam Gyu Ri. The genre is an espionage period drama, with a slice of romance and family drama. The action scenes are heart-stopping that by watching it, it feels like you're there also.

Please take time to watch the drama and see for yourself why I rated this 10, my second all time favorite kdrama, Lee Hae Young became one of my favorite actors and lastly, why I'm obsessed by the PD's period dramas.

It has a similar premise, though it is a romance between a man and a woman.

guy from modern time switches body to person from past. In mr Queen modern guy wakes up as queen in Joseon era. One actor (in Mr Queen actress) portrays two characters-so well done, you think they are really 2 different individuals.
Mr Queen is very funny, very original and different from 100 times seen dramas and Actress does phenomenal job.
