I <3 manga like:

• Runroi Kenshin
• Hachimitsu no hana
• Kaze Hikaru

I want to find more manga like that or something like Fushigi yuugi (series). I tried reading REd River and From far Away but it wasnt very engaging...

I'm guessing you like the historical settings. In that case I suggest

Historical Oriental setting
Shin Angyo Onshi
Amatsuki
Inuyasha
Basara
Vagabond
The Bride of the Water God
Tactics
Seven Swords
Mugen no Juunin
Kingdom of the Winds

Historical Western setting
Apothecarius Argentum
Count Cain
Asklepios
Belmondo le VisiteuR
Princess

That's everything from my lists I can think of. Hope it helps.

The pen is mightier than the sword...and considerably easier to write with.

Similar to Fuushigi Yuugi sorta plot... you could try Haruka (it's a reverse harem, so maybe that's not your thing) or Saver? I highly recommend Saver, it has awesome art and a unique female lead.
