    Can’t wait for this! Hope story’s good and the drama will have high ratings. Fighting!

  16. 16 : iammee Says:

    Another great romance comedy to watch. Nam JiHyun is a pro at doing Historical dramas, she is such a beautiful and a good actress. Although I became too attached with Nam Ji Hyun and Ji Chang Wook from before, I am please to see her being teamed up with other good looking actors. It would be so nice if the lead actor is Kim Su Hyun but DO is promising actor so it’s not so bad. It’ s a wonderful first 2 episodes.

  17. 17 : Jeyel Says:

    Perfect role for D.O…. <3 Great Role For him. Good also for Nam Ji Hyun she is a great actress.. This is will be fun drama for a year.

  18. 18 : Rhusselle Rivera Says:

    aw Ep 1 is great 🙂 more to come yay

  19. 19 : Larisa Says:

    Do you often go to the gym? I walk 3 times a week.

  20. 20 : Shosh Says:

    This Drama is so cute, I don’t like old dramas. But this one really nice for a change. I imagine how hard it is to set the choreography and how to get the right effect and play from the actors and actresses

  21. 21 : ally Says:

    This drama reminds me of “The moon embracing from the sun”.. D.O is like a copy of Kim Soo Hyun!! I love his acting and the drama is great so far!! Stotyline is relaxing!! Fighting!!

  22. 22 : dodee Says:

    I love this drama so far, great acting very funny, I love it. The prince is so relax being a normal citizen but he still talks proper. The royal palace, they are so stiff in everything. I hope all the episodes would be entertainin all the way. They’re married yayy great!!!! Hope to see some children that would be sooooo awesome. I wish the ending would be cute like Grand Prince and The moon embracing the sun. Cheers!!!!

  23. 23 : Sinopsis 100 Days My Prince Says:

    nice drama!

  24. 24 : Ae Sin Says:

    The male lead is awful. No depth in his acting. FFS somebody should have helped him out.

  25. 25 : Jean Dy Says:

    I love the drama, it’s great. i love the male lead too. His acting is on point. Not so great but def not bad for an idol-actor. recommended

  26. 26 : lili Says:

    This historical drama is highly recommended to watch!! kudos

  27. 27 : Papang1387 Says:

    The drama of the year !! <33

  29. 29 : Rhusselle Says:

    Ep 10 worth it to watch made me giggle, cry and laugh 🙂

  30. 30 : fran Says:

    What is the reason ep 11 has not aired. I hope this not another drama that gets cancelled in the middle it was just getting to the meat of the plot.

  31. 31 : Karyn Says:

    It is not canceled.. Drama Fever was shut down by WARNER BROTHERS and I don’t know about others, but I can’t find it airing on any other k-drama websites😭

  32. 32 : Negin Says:

    I can’t see any chemistry between mains. The main actor is not good for being romantic and his way of the gazing is just the same in all the scense

  33. 33 : Kim Lau Says:

    This historical drama is highly recommended to watch !
    I love the drama, it’s great.
    D.O. and Nam Ji Hyun Good acting !

  34. 34 : Silverswan Says:

    This is one of the best historical drama I even watch. The Main actor and actress are suitable for this drama, and I love it. It is not ending yet but I do hope they can win for this one and thanks to

  36. 36 : Sari Says:

    My first favorite saeguk drama.. (>.<)
    Its really enjoyable, easy to "digest", funny but also romantic..all the cast were act very well, including the antagonist lead..

    I really wish there are some scene about Crown Prince and Hong Shim wedding in the palace..or when they play with their children..guess I wish the episode more longer..heuheu..

    But anyway, congrats for the high rating !!!
    Thanks to all actor, all actress and all crew..

    Hopefully we can see DO & Ji Hyun play on another drama as a couple ..

  37. 37 : N Says:

    Can’t believe that this has already ended. I’m missing their village days already.

    I’m impressed by the acting of DO. He plays his role really well.

    Highly recommended! ❤

    Great drama, worth the time. Good watch. 🙂

  41. 41 : DeeAn Says:

    Boring!! The storyline is slow. Less conflict but to long for solved. Arrghh so exhausting !!

  42. 42 : Kay Says:

    Such a fun historical with a nice story. DO and Nam Ji Hyun were great together 🙂

  43. 43 : Sandy Says:

    I absolutely love historical dramas, but I didn’t really care for this one as much. The story dragged with not much of anything happening. Also, very unrealistic on many levels. I’m trying to hang in there at ep 9, but it’s hard.
