I'd say she's versatile enough for a melodrama, and way more ready for a lead role than some people who keep getting offered lead roles despite having nothing to offer, artistically or otherwise (and by otherwise I mean popularity).

Though Moon Geun-young is not one of those people, she at least has talent, experience and a fair degree of Korean public recognition on her side.

Han Groo is versatile enough to take on the lead role speaking from an artistic point of view. What she lacks is face value. I hope she chooses her next project well be it first lead or the second. The thing about female second lead is most often they are so stereotypical and predictable that I fear her talent will go to waste hence really don't want her taking it up. Moon Geun Young and Perk Seo Joon aren both excellent. I am 100% on board if they decide to join this drama.

Well, I'm not sold so far on her more subtle acting. She's the hottest actress when it comes to physical or madcap comedy for sure, but melodrama, especially by this writer, is a very different challenge.

Ha Myung-hee loves static dialogue scenes with sparse mimic and almost no body action, which is the opposite of Han Groo's actual expertise (she would kill the "table sweeping" scenes though). A lead role in this drama would put her in very uncomfortable scenes, like, 80% of the time.

Han Groo is fairly new. From what I've seen, I think she is capable of delivering and she can step it up. MND was loud but it also had little moments that gave her ample time to shine. There was this part in episode 1 where Han Groo's character is drunk and goes to find her ex-boyfriend in his restaurant to just get answers. There is a moment where she realizes that it was all a lie and at that moment she just stood there and her eyes spoke volume instead. I was sold to the drama right at that moment. I believe she has both the capability and range as an actor to pull a melodrama. But that would be possible when she is cast in one and has the chance to show her acting . Lets see, like I've said before, I am already in for this drama even without her in it. I just want her to accept the role even if it is of second lead only if its meaty and different. Not the usual kind.

Han Groo was excellent in One Warm Word, and that drama was as melo as it gets and had almost no comedy. She could do a role like this no problem. Unfortunately I don't think a big three network is willing to take her on as a lead yet.

@Laica

"One Warm Word" might be melo, but Han Groo's role there was mostly comic relief (with some angry big acting later on and some rather bad crying scenes).

Just look at the clear difference in acting style between the two female leads and Han Groo in that drama. Both leads carried a frozen face through 90% of their scenes and had less mimic action during the whole drama combined than Han Groo in a single scene.
