Dramas like Hana Yori Dango / Moon Lovers

Hey there!
I really need help! Lately I've been nostalgic, always thinking of Hana Yori Dango (one of my favs dramas) and Moon Lovers. I just need moreeeeeee!
So... if you know any dramas that give the same vibe as these ones please let me know! I've been really struggling with this ^^'
About HYD, I've seen all versions already and I saw Moon River and The Heirs that were similar... As for Moon Lovers... I'm actualy a newbie i historical dramas and that is my first and only try (not counting with moonlight drawn by clouds wich I'm currently watching)
Now, please give me some recommendations, I need something to see, badly ^^'
Bye ya'll
