Kyou Kara Omega ni Narimashita
Uke was beta turned omega, mutual feelings but neither realized (or is that mutual unrequited pining? Nah, mutual pining I think) Cute, respectful, mostly misunderstandings that drive 4 chapters
Beware of the Brothers!
Ending fell off hard and translations were bad to boot which didn't help. One of those where it seemed like once they mc reaches adulthood the whole story loses its pace. They seemed too childish even as adults too :c wasn't satisfying
Aijitsu to Hanayome
One of the best omegaverses. Has an omega origin through the decomposing body of a god. Beautiful relationship between the main couple. Just so good, and a kid at the end you don't see too well. Also full of consent and waiting until both were okay with it and their plans done b4 mating bite (last chapter). I loved everything about this
