Well i am looking for a Seinen with a interesting plot and Innnocent light toned romance /with not much angst/ and if possible with some slice of life feel to it...and also not much Adult-ness ecchi..
Some Examples would be..
Blood Alone(Perfect example)
Chocolat /Seinin/

Thank you for you Help ^^..

I dunno those are kind of hard attributes to all bring together in a seinen manga...

Yumeka Sumomo/Sahara Mizu's works..?

chokotto sister
koi neko
kamichu!

Planetes is great! though the romance is not the focus... it's more like... it has themes that have to do with love... I think it had a sweet ending anyway 🙂

I highly recommend these threads: 01, 02, 03.

also Emma fits those characteristics... very slice-of-life ish and romantic... although it is classified as seinen it could be josei
