Himari is a beta who can't help but be a little jealous of omegas since all her relationships end since she doesn't enjoy sex. Kou is a doctor Himari hates for trying to buy the land out from under her parents' restaurant. At Himari's next phyiscal though, Kou triggers Himari's heat, and the two find out they are alpha and omega andthey somehow got bonded without either of them ever realizing it. A lot of forced and unbelievable things just to make the plot go forward. ️Trigger warning: dubcon(heat)

Imitation Mate

Complete | Makoto Kashiwagi | 2000 released

Tsukasa is a high spec alpha who hates omegas and works hard to stay at the top. One day he runs into his former high school classmate Yoshiki, also an alpha, working at an arcade, and he's surprised by how different their lives are. After a drink and a bet, Yoshiki talks Tsukasa into having sex and the two become sex friends. But the longer this goes on, the more we learn about their strange relationship as maybe friends, maybe rivals, and maybe more, and Yoshiki's strange fixation on Tsukasa. But when Tsukasa's body begins to change, he worries Yoshiki won't want him if he's not a perfect alpha and begins to pull away. Yoshiki is a terrible person, but I will say, I think that makes this one interesting, although it leaves it with an unsatisfying end. Trigger warnings: dubcon, attempted rape, lying/manipulation, stealthing.

Koishite Baby (MIYAKO Mimeko)

Complete | MIYAKO Mimeko | 2019 released

Kiyo is an omega with a surprisingly big stature who makes his living as a pole dancer, and Chiaki is his alpha childhood friend who has always taken care of Kiyo without realizing Kiyo is in love with him. After Kiyo puts himself in a dangerous situation and Chiaki saves him, his feelings come out and their relationship begins, but Kiyo is a bit of an airhead and prone to jumping to conlcusions, leading to some crazy bumps in the road. Not to spoil anything, but I think the conclusion to the first major conflict in their relationship is buck wild (and kind of a quick resolution that makes everything okay, but less interesting). Still, a cute couple (with a rare, bigger top) and a fun read. Trigger warning: attempted rape(?)

Levi(alpha) and Eren(omega) have been dating under the assumption that Eren is a beta, and since Levi is a "defective" alpha who can't get hard or have children, he enjoys it assuming it will end one day. But when it turns out Eren is an omega and they're a pair, Levi is distraught, realizing that he can't give Eren a child, and childless omegas are looked down on and not helped by the government, so he wants to break up. But Eren isn't having it. Trigger warning: child exploitation(experimentation).

Mitsuya Jin (omega) has unstable heats ever since he had his omega gland removed to end his pairing. One day while seeking a hookup for relief, he almost gets gangbanged and he's rescued by passerby Tosaka Eiji who takes him home. Mitsuya tries to seduce Eiji only to find out that Eiji can't sense pheromones, so he seduces him more directly then kicks him out. But it turns out that Eiji is his new neighbor and ends up working at Mitsuya's cafe, so things can't end as cleanly as he hoped. But just when Mitsuya is starting to get used to relying on Eiji, his ex-lover Jino reappears, the man who paired with him and abandoned him in the past. Interesting and well written, though I really don't like Eiji's haircut in the second half. It was cute long! Trigger warnings: attempted rape(gangbang), cheating, stalker, violence, child abuse (psychological).

Yoji Tsuchiya(omega) has had a crush on his classmate Jin Arumi(beta) for a long time, though he knows nothing will come of it as Jin just sees him as a buddy. But when he goes into heat in front of Jin one day, Yoji can't stop himself from taking advantage of the situation to finally have Jin to himself. After that the two can't keep their hands off each other, but Yoji blames himself for using his omega pheromones to seduce Jin, while Jin becomes increasingly aware of how little he knows about omegas. Cute, non-traditional omegaverse relationship. Trigger warning: attempted rape

Shishikura Yu(omega) is depressed that everyone around him is getting married, so he signs up for a pheromone matching service, and to his horror he's matched with Kotani Haruto(alpha), his new coworker and nemesis from middle school. When Shishikura goes into heat with no one else around, he can only ask Kotani for help, and the two sleep together, starting a physical relationship, but both insist that they still despise the other. But when Shishikura's family pushes him to meet with another alpha for an arranged marriage, he starts to realize his feelings for Kotani, all while thinking it's impossible for them to actually be together. The second volume deals mostly with Kotani's issues with his family. I like this couple a lot because they're both well-developed, they have realistic and interesting interactions, and they're just fun together, so it's a good read. Trigger warnings: dubcon(heat), discrimination, noncon.

Ao is an omega who's body type practically makes him a beta, until one night he's coerced by the alpha Reiji into letting him stay the night, and Reiji rapes him. After that, Ao's previously controlled heats go crazy, and his life spirals out of control, while Reiji stays with him and helps him deal with all this. But Ao is caught between wanting his old life back and wanting to accept Reiji and this change into a full omega, a feeling that is made worse when he learns Reiji planned this from the start. The moral of this story seems a little wack, and Reiji is a terrible person, but I like Ao. Trigger warning: rape, discrimination.

Anti Alpha

Complete | Okuda waku | 2019 released

Sena Yuujin has always payed special attention to his classmat Kamishiro Ren, a childhood friend of his governmentally assigned fated pair who seems to always be the best, but when Kamishiro happens upon Sena having sex, he goes into heat and both realize that he was actually an omega but his family hid it, even from him. Sena forcefully proposes to keep Kamishiro's secret if Kamishiro will sleep with him, which will also help disguise his omega pheromones, after which the two are at it all the time, even as Kamishiro hates himself for submitting to this sex that proves he's no longer an alpha. But when Sena announces he's breaking off his pairing with Kamishiro's childhood friend, Kamishiro reaches his breaking point and he's forced to confront exactly why it matters to him so much that he be an alpha, in the first place. The second volume shows their relationship 7 years later dealing with Sena's evil uncle. I think the subject matter for this one is rough, so don't read it if you're squeamish about sexual assault, but the characters and their inner turmoil are really well done. And while their relationship is dubious in the first half, it's pure gold in the second half, and I highly recommend. Trigger warnings: coercion, rape, attempted rape, discrimination, forced confinement. Ch.5.5-5.7-This is the side story of Kamishiro Rei's uncle, Kamishiro Sei, who realizes he may be an omega after Rei comes out to him. Meanwhile, he's taken on the case of alpha Takishiro Ruiji who confined and nearly killed his partner and is now living with him. When Sei stops taking the pills from his family doctor and goes into heat, the two sleep together, but Sei is afraid to let the world know he's an omega and to believe in the love of Ruiji. Not my favorite, I usually skip it. Trigger warnings: forced confinement, rape.
