WorldBear's Manga

Honestly my favorite by this author. No pushing, questionable consent sex and a relationship pace that makes some sense. I wish the story went longer, so you could see them grow even more, but overall it's a sweet romance with just the right dash of angst and drama.

Girl is an adorable space cadet, but not in a cliche way. She is passionate about what she loves and it's lovely. I also like that the guy isn't a total ass to her. They have lots of potential.

2) Pinup Boy http://www.mangago.me/read-manga/pinup_boy/

Definitely the fluffiest omegaverse story out there.
If you like the idea of the omegaverse, but aren't a fan of all the angst and rape, then this is a great story for you. Lots of cute family moments and a happy alpha/omega couple who chose to be together and have a family.
