I'm desperately seeking manga (or any comic!) which would be a romantic story of a young woman and older man.

There are several age gap mangas out there, but the problem is that the girl is often somewhere between 16-18 and guy is 25... tops. And I'm 30. I've always liked way older men, even as a teenager I used to fantasize from middle-aged men to even older - give me Harrison Ford, Colin Firth, Tim Curry or Sean Connery anytime!

So where are all refined, well-mannered older men who can make you blush all over just by a teeny smirk?

Oh, and pretty boys are always a nice sight - but older men need to be MEN. I'm talking about beard, short, stylish hair (while reading Emma I was more drawn to William's dad xP) and being smart, handsome and... manly.

COPYPASTED FROM OLD MAN YOUNG GIRL ROMANCE!? THREAD

Ojikoi
Ristorante Paradiso Haven't read it (yet), but the anime is awesome.
Nioi.
Tomodachi no Papa - Hakui no Oji-sama (Smut)
Fugitto Amor (With a twist)
Jinbe

... By the way, Oyaji Romance tag is what you want. Not much there but...

~4400 manga completed
~1700 ongoing...

You can try this too: &

It's a love triangle but it's reaaally nice.

Thanks Aremon;

Ristorante Paradiso is familiar (I've seen the anime, it was just waaaaayy too slow and never got anywhere, nice-looking though).
Ojikoi has an older male character that's described as useless, so not doing a thing for me. Also he looks a bit too carefree. Nioi I couldn't find anywhere, but it could've been good.

Alright, so several of these have 40+ male leads, but I included those in their mid to late 30s as well. If I remember they're 40+, there'll be a plus sign next to it. (Though oftentimes the older the male, the less the age gap)
