So basically I'm looking for a manga (preferably Shoujo/Josei/Seinen) where the main couple are a College girl and an Adult guy.
No one shots or manga with collection of stories please...
I prefer if it's full length and only focus on one couple..

Here are samples that I've read:
Coffee & Vanilla
Kawaii Hito (SAITOU Ken)

Thanks in advance!!!!

Help!!
Aisuru Hito
Also Devils Line, this one not focus only on romance but it's pretty prominent so far.
Hana no Namae, started from the girl still in high school but she entered uni pretty early, like at 2nd chapter or so.
And there's Just One Smile is Very Alluring, the guy started as a last year college student so halfway into the story he graduates and becomes working adult, at least that's how it is in the drama version.
