Shoujo and josei series set in the modern day with romance between adults. no teenagers or high schoolers, I'm tired of reading about kids LOL.
college is in a separate list:

warning: mostly wholesome content, but some may have smut.
After reading a lot of josei manga, there's a lot of bad ones and some actually good ones.
My ranking can be rather subjective. I don't like cheating so I will avoid it as much as I can. Also don't like harem so I avoid that too. Consent is important so if it starts out pretty sus I will be lowering it down one point. I will judge it based on the story, artwork and smutty.
Quality is also important so if it is trash...you'll know it's trash.
part two is available
