Joukakei Kareshi
Love the art style... the second couple, specifically the beta, is just the absolute worst though. There is no forgiving how he treated the omega.
Youchina Koi O Dou Shiyou
This one makes my heart ache a bit.... the MC is an omega who has just an awful life. Abandoned and treated like shit by everyone, included being raped, he sells his body just to make money to escape from the town. Then he falls in love with the new guy in town who is quiet but takes care of him. So touching. Update please!
Tsuki no Ura wo Koete ~Omegaverse~
Will there ever be an update? Only one chapter and I'm curious where the story goes.
Abarenbo honey
ok, I really disliked this at first with what is essentially a rape scene when the omega's heat hits in the middle of a fight, but suddenly it gets pretty cute. I found myself for attached to Misturou's story. I liked that he was a strong, composed omega despite his unfortunate upbringing.
Unmei no Kisu wa Oazuke
A strong-willed omega working at what seems like a sort of host club meets a stiff, formal handsome alpha and they don't immediately get along but the second they touch there's a spark that leads the alpha to believe they're a fated pair. I like that the alpha is gentle and sweet and doesn't force himself on the omega, instead he's using a lot of restraint and courting him. Loved this.. so sweet.
Shingeki no Kyojin dj - Fan Service - Omegaverse
I haven't watch a whole lot of Attack on Titan but this was pretty hot, not gonna lie.
Yuri on Ice!!!- Eros: Captured in the Pleasure Garden (Doujinshi)
Yuri is an omega and in love with Victor but keeping bot a secret. Victor suspects something's not right and when he has drunk sex with Yuri he's even more convinced and flushes his heat pills down the toilet. Great art-style. Hoping this is updated soon.
Immoral Sandwich
So, the lack of enjoyment from the omega is kinda off-putting but this is still pretty hot and things are developing so we'll see....
Kashikomarimashita, Destiny
Sweet and heart-warming. An omega son of a wealthy, well-connected alpha family is left alone with only his beta bulter after his parents die and is taken in by a family that was friends with his. The son of the head of the family is his soulmate but has struggled against acknowledging it since they were children because he's sick of having no choices in life. But one day the omega goes into heat and they are pulled together anyway. This manga also goes into the personal life of the beta butler and his romance with a fellow butler who's an alpha. That's also super sweet, maybe even more so. ETA: This manga turned out to be way more about the butler couple! It seems rare to find so many good feels in an omegaverse story but there you have it. This is probably THE BEST omegaverse manga.
