hai all

I want a manga in which art is present..any art like litearture,painting personality,music personality,film maker.. etc.

A boy and a girl.. romance should be there.
an interesting plot i want.

new scenic designs.. new characters.. a fresh feel..
please suggest me romantic in the backdrop of any art.. and with a decent storyline.
A straight forward storyline..
Like growing romance...in between some conflicts...something like that..
A perfect story i want.beginning... middle... end... these three should be perfect.
A complete interesting story.

does it have to be completed?

I didn't like it but Film Girl I guess...
Yumekui Merry yumeji writes, isana draws, but it is NOT the focus of the story, it has a unique scenic design though
Taiyou no Ie she writes a cellphone novel
Akuma to Love Song obviously music
Natsu no Zenjitsu adult content!
Shigatsu wa Kimi no Uso interesting but not that many chapters...
Tonari no Kashiwagi-san she draws moe art (I think)

Hachimitsu to Clover well they go to art college
The Sleepy Residents of Birdcage Manor model and painter

sorry most of them are ongoing...

in need of romance?
uncommon, sad, sweet

Ashita no Ousama - theatre

AKB49 - Renai Kinshi Jourei - idols

Beck - rock musician

Yesterday o utatte warning: extremely slow romance

Hakuji - romance between young painter and his muse

Nousatsu Rock Shounen music
Bakuman manga
Lovely Banchou manga
Dear Green photography

I second The Sleepy Residents of Birdcage Manor.

Watashitachi no Shiawase na Jikan - the heroine plays piano (major plot point)
Koe de Oshigoto! - May not be your cup of tea since the "art" they make is eroges.

Being alone is only lonely if you want it to be.
Staying in lucid delusion for an eternity.

Tenshi ja Nai!! -->idol
Charisma Doll -->singer

Angel voice not that bad and it has to do with singing I haven't read it in a long time so I will give you a summary
-A chance meeting between a famous idol and a ordinary girl on a snowy surreal day set the stage for the manga. Depressed and hopeless, Kurashiki Yuya meets Mayu, whoose carefree and lives-for-the-moment attitude brings him new hope. In the spur of the moment, Yuya forgets to ask Mayu's name, and watches as she disappears from his life. Much later, Yuya comes across Natsume Tougo and their band Dessert, along with there new performer, who is none other than Mayu. Mayu and Yuya meet again, but Tougo is determine not to let her go at any cost!
