C-Blossom - Case 729

THANKYOU! (

decent art please (meaning no Angel Densetsu )

Skip Beat! - it's not actually your classic shoujo-romance manga, but it beats ALL the rest
Meru Puri - Though the translation is crappy >_< (or anything from Hino Matsuri)

Good Light-hearted Romance?

Hana to Akuma <-- Cute but sometimes annoying in my POV..
Hana no Namae <-- so heart warming....
Antique Romance <-- Love this!
A Kiss for my Prince <- nice too
Sugar family <-- You'll LOVE it!
Romeo X Juliet
Present

Smut-Romance?
The one-shots from >>HERE<<
Black bird
Pink no idenshi
Bocchama wa Ijiwaru
Shinobi no Onna
Shura to Otome <-- Read the one-shot called "Nude tribe"
Otoko Hime to Mahou no Lamp <-- Read the 1st and 3rd story

The BEST ROMANCE/HISTORICAL manwha that I've read is 1001 nights..

Even if you dont like Shounen-ai, this manwha actually have mini-stories related to legends and myths which has Het pairings.. like Cleopatra...Turandot..etc..It's a very very EPIC manwha!

and try reading this >>one<< too..Tell me if you liked them!
