Kawaii Sensei
English teacher Miyata has never gotten along with jock types, so when he's assigned to supervise the kendo club with Samehara as the coach, he thinks he and the other teacher won't get along. However, spending time with Samehara, he can't help but find himself interested in the way Samehara always seems to be wearing a mask to keep others from getting too close. When he finally uncovers Samehara's secret, he's gay, Miyata is more interested than ever and immediately starts pressuring Samehara for a relationship. But Samehara can't trust Miyata's flirty nature, especially when he's long since resigned himself to a life without love. No trigger warnings.

Pheromoholic
Ch.1-9.5 - Towa is a clownfish/rabbit chimera who has been warned that his species attracts everyone, but especially lions, and they need to stay away or risk their own downfall. But he's also a model, and when his company brings in a new group of carnivores, low and behold, two of them are lions, and one of them is Issei, a man who Towa met at a party many years ago who instantly seemed to awaken his desires. Though Towa tries to stay away, Issei is persistent, but even if Towa is willing to be with a lion, will his family allow it? Trigger warnings: dubcon, noncon. Ch.5-6 - Stuck in the middle of the above story, we have Ririsu(Lillith), a nurse who's getting stalked but finds it exciting and his student Adam, who is not about to let this nurse go.

Anti Alpha
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.
