Korean Remake: Tell me your perfect ML and FL

Lighter and Princess was heavily carried by the two main leads and their perfect intense chemistry. 

Now I wonder, if there would be a korean remake, which korean actor/actress could pull it off?

I thought about this for a whole day, and i just could not think of anyone, but maybe you have suggestions. I would love to know.

I am also eager to hear, what variations in the storyline you could imagine for the drama. Where would a korean production change things and make it maybe an even better (or maybe more annoying) storyline?

Idk much of younger Korean actor/actress but perhaps Lomon (he could look both fierce and flirty) for Li Xun and Kim Yoojung for Zhu Yun (because a princess, of course) 

For me it would only work if they cast young actors, rookies or those who do not have any previous notable roles yet. It's better to start with a clean slate on this one.

Idk about Korean, but for a Thai remake, I recommend Bright and Tu from F4 :)

I'd say Park Jeong Min for Li Xun (I know he is more on senior actor but he has very young face) and Lim Yoona. Their chemistry in the movie was palpable

Kim Yoo Jung as Zhu Yun

Kim Min Jae as Li Xun

Or for lesser known actors:

Kim Min Seo as Zhu Yun

and as Li Xun, any of the following:

1. Jeong Yun Ho 

2. Kim Young Dae

3. Park Ji Hoon

4. Kim Kyung Nam

Both Korean and Thai remake would be just fine for me since i love both hehe. But i hope Korea will do well haha i got quite disappointed on their remake of ALSB.

For Korean, I would like to see Kwak Dong Yeon and Choi Sung Eun.

Junho's role in Just Between Lovers reminded me of this one a bit, but it's hard to say who could pull off such a young role.
