I have to say, the child actors were better than the adult (in my opinion). I started the drama thinking that I would have to struggle through the first episodes, but actually I'm losing interest now. It's too bad, because I was anticipating a juicy role for Chun Jung Myung after Cinderella's Sister.

where can i watch this online? ive seen site hosting videos in raw korean only.... :(

well i hope it should get more interesting. i was planning to watch but i guess just have to wait some more feedbacks then.

I thought i would love this drama because the child actors were so good but now i have no interest with the adults. Also i wish the pairing would be different too i actually like Dal Yi more. Oh well....:/

I was hoping the adult actors would improve this series for me but I was disappointed.

Maybe Chun Jung-myung was never meant for sageuk. So sad.

I liked the kids too, which I often do in sageuk. But the story took forever to do the simplest things and the English subbing at the site I was using was just awful. I dropped out after 6 episodes. So I guess I'll never see CJM in this, unless it comes back with higher-quality subbing at dramafever or someplace.

surprisingly, i found the kids a whole lot more compelling than the adults. i really wanted to watch it for pie but i think i'm going to drop this one. episode 10 was just so meh. and i am not a fan of han ji-hye's character here. she's such a snob. off to start twinkle twinkle now.

Honestly sageuk and CJM don't mix. I love him so much I could be dazzled by him eating some CF endorsed strange ham but The Duo.....I just tuned out. Hopefully he can go back to Romantic Comedies again....I miss the What's Up Fox days...

i had to disagree with you all , i find this drama interesting , CD character is very hard to act , i find this actor acting skill is excellent , he delivers his character well , i can feel his pain deep inside .

I love, love, love CJM too! Since I've watched What's Up Fox. Didn't get to finish Goodbye Solo... got bored around episode 3... Have not gotten round to watching Fashion 70's... Cinderalla's Sister gave me a headache story wise, but I think CJM did what he could with what he was given... in The Duo, the kids were indeed good! I have just finished episode 11, so I haven't really warmed up to the adult characters yet... The story has yet to reveal who (personality wise) they have become. But then I don't know if it's because the eng subs in certain parts were not as helpful at it should have been but still, I admire and thank the subbers for the effort. And yes, i think I'll continue watching.

i haven't seen a single episode of this (nor read recaps) but i like these photos, esp. the last one.

I've enjoyed watching this drama so far. The story may move a little slowly sometimes, but the characters are so compelling and the women have real personalities and character.

I'm enjoying this drama. The pace seems slow,but it doesn't bore me. I think CJM's character is hard to define,once he became an adult. I'm up to epi 12 and,I'm watching till the end! CJM's acting is good,given the character he has to portray. The adult Dong Nyeo,I'm confused about her personality. could be the acting,but maybe,her character has yet to be fleshed out.

The Duo's a solid drama and a welcome contrast against MBC's run of sageuks -- it kinda follows the lead of Chuno in trying to portray an amoral and gritty slice-of-life panorama, and in Jejoongwon in trying to create a heroic man-of-the-people vibe.

Chung Jung Myun isn't bad here. He's just . . . emo. Chung Doong seems like he should be written as a would-be Iljimae or Sung Baek, but he seems kinda passive aggressive and dull.

Lee Sang Yoon is excellent as Gwi Dong. He has the easiest time with the dialogue, and Gwi Dong seems palpably

I think Han Ji Hye's Han Ji Hye. She instinctively plays up the bitchy, snarky, lecturing aspect of the character, which IS appropriate for Dong Nyeo. It's just that the mix of Dong Nyeo's moody self-regard and Chung Doon's loser boy in love makes for a rather tedious romantic pairing. It hasn't sold.

Personally, I think Duo would be better had the romantic heroine been Dal Yi. Her saucy, gunslinger ways seems written out of an American Western, and she had great chemistry with both guys. The child Dal Yi was the standout among the child actors, but unfortunately I see little of that persona in the adult version.

haha it looks like some people rushed to judge this series (me included). First 9 episodes (the ones with the child actors) were so great.Next 4 episodes were also pretty good (the arirang-dance scene from episode 13 was one of the most beautiful scenes yet,it reminded me of 'seopyenoje'.). Then,from ep.13 onwards (some would even say "from ep.10 onwards") , "the duo" started to feel really dull , i was disapointed and i'm sure i was not the only one. I even wanted to abandon the damn thing, that's how bad it was compared with the strong begining, yet i continued watching it using the fastforward button most of the time.
And then, all of the sudden, without any notice, BAM ! From ep. 18 onwards (18 included), the series is one of the best korean sageuks ever made, not only that it started to be good again , but it's even better than the first episodes, i was shocked to see that it got back on track! I'm so happy i continued watching it,i would have lost one beautiful jewel. You guys should do the same, don't stop after 10 episodes ! Although there are a lot of boring episodes after the kids grow up, you will get rewarded after
