More than a Play Bite
Ch.1 - More than a Play Bite - When Takumi was a child, he was rescued when he fell in the river by a wolf beastman who lives nearby called Professor. Now in university, Takumi finds himself wanting more from their relationship, but Professor still treats him like a child. When Takumi finds out that beastmen play bite their lovers, he becomes determined to overcome the gentle care Professor shows for him and get him to mark him. But Professor is scared to hurt the little boy he watched grow up. This one isn't my favorite, but it's fine if you're into age gap stuff. No trigger warnings. Ch.2 - Catch the Goddess by the Tail - Shunsuke is a leopard beastman in the track club as his university who has a cocky underclassman, Aihachi, who always says the goddess of victory is on his side. Before a big race, Aihachi always calls Shunsuke over to cook for him and they end up sleeping together, and Shunsuke isn't sure why he goes along with it, except that he loves to see Aihachi run. But when Aihachi gets even bigger wins, Shunsuke starts to feel that Aihachi doesn't need him anymore, not realizing that Shunsuke has been his goddess of victory all along. The story is fine, but mostly I really like this one for Shunsuke, who does a great job of being nonchalant but also completely not in touch of his feelings. No trigger warnings. Ch.3-4 - The Sweetest Bite in the World - Mikuni is a snake beastman who was always made fun of until his recent molt, which has made him not only beautiful but unresistible due to his pheromones. With hordes chasing after him every day, the only one Mikuni really wants to notice him is Nachi, a half-lion beastman who protected him when they were children, but Nachi seems unaffected. Mikuni is desperate to get Nachi's attention, even going so far as to bite him with aphrodisiac venom, not knowing that Nachi has only been looking at him all along. Trigger warning: aphrodisiac, attempted rape. Ch.4.5 - More Than a Play Bite Extra - This extra is very cute, and includes all the previous couples going to consult with Dr. Mikami, a snake beastman, and his human assistant. It's fun to see the couples again and get a deeper look into how their relationships progressed, but honestly, Mikami and his assistant are my favorite couple in the entire volume. I love them and wish there was more. No trigger warnings.
You Are So Lovely
Shin Juhyeok is a hardened gangster, but one day he picks up an orphaned wolf on a whim who turns out to be a beastman, Lee Haewon. Haewon grows up quickly and Juhyeok can't help but spoil him, but with Haewon reaching adulthood, he now needs someone to help him through his heat periods, and the only person he wants is Juhyeok. Juhyeok can't help but give in this time too, but on one condition--they're not a couple. This relationship is only until Haewon finds someone else, no matter what Haewon wants. Meanwhile, crime things going on are putting Haewon in danger. Not bad so far, as long as you're not squeamish about parental figures as love interests. Trigger warnings: incest themes (guardian x ward), dubcon(heat).
Akatsubaki
Sakichi lives on his own near the mountains, shunned by the villagers for his different hair color. One day while working in the mountains, he finds an abandoned demon baby who he can't bear to leave to die, so he takes the demon in and names him Aka. Although Aka can't speak or understand human language, Sakichi finds joy in seeing him become more human, until one day he realizes that perhaps putting human expectations on Aka is only hurting him, and he should be free. But even then, Sakichi can't bear to let Aka go and searches him out years later, but this time, the relationship turns sexual. Honestly, this story is very well done with some absolutely heart wrenching moments that make me cry every time, which is why I keep coming back to it even though the relationship is gross and obvious grooming. I don't fully understand the ending though. Trigger warnings: child abandonment, discrimination, incest themes (adopted father x son), grooming.
