Not a simple gap like 9 years (or such), but something well above 10. Like, 20, for example. Also, this "older" man should please look his age, with wrinkles or something like that. I don't want the manga to say he's 40 years old, but then he looks 20 and no older than his romantic partner. This is literally the biggest point: HE HAS TO LOOK HIS AGE!
And, please, dear lord, no loli or shota partners. I don't mind if his romantic partner is a little young (plus-minus 18), but not if they look like they hadn't even reached puberty.
No Tragedy either.
Also, no hentai, please. (However, I don't mind smut.)
I don't mind yaoi either, but no Naono Bohra works (I already read all her works).
Examples:
Jinbe
&
Miman Renai
Kore wa Koi no Hanashi
Nocturne (PARK Eun-Ah)
(My favorites: )
Ojikoi
Otoko no Isshou
Ristorante Paradiso
Mitsu-Koi
Tomodachi no Papa - Hakui no Oji-sama
Shuuden na Kankei
Harem Days
Hada no Ue no Renai Jijou
Renai Nenrei
Pillow Talk + Holiday
Zurui Otoko (NAONO Bohra)
Also, seeing as I know I'm not the only one who struggles to find things that fit my taste, I advice those who like these manga, you should take a look at FR: Pub Encounter on your play store.
